An extra semicolon was left in the nvgpu_log() macro. Remove this
semicolon.

Move the Linux specific header files to include/nvgpu/linux/ to keep
the header files more organized. Having tons of Linux specific stuff
pollute the top level include seems like a bad idea.

Update the debugging APIs in nvgpu to be more coherent and less dependent
on Linux kernel APIs and data structures. The old API is maintained for
backwards compatibility but the prints themselves are changed.
The old API now prints stuff like this:
[ 46.376077] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 508
[ 46.376242] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 509
[ 46.376359] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 510
[ 46.376466] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 511
[ 46.376604] nvgpu: gk20a_fifo_update_runlist_locked:3090 [DBG] runlist_id : 0, switch to new buffer 0x 4003a0000
[ 46.378348] nvgpu: gk20a_mm_l2_flush:5259 [DBG] l2_flush_dirty 0x2
[ 46.378562] nvgpu: clk_config_pll:170 [DBG] low_PL 1(div1), high_PL 2(div2)
[ 46.378684] nvgpu: clk_config_pll:170 [DBG] low_PL 8(div8), high_PL 17(div17)
Each line starts with 'nvgpu:' since this is the nvgpu driver. Then there's
the function name which is is right justified and post-fixed with a line
number. This keeps all statements lined up so long as the function name does
not exceed the length of characters alloted for function names (33 currently).
Lines are also left justified with 4 available spaces since there are currently
no source files with over 9999 lines. The type of message (DBG, WRN, ERR) is
then printed in brackets. Finally there's whatever message is to be printed.
The new API will be largely the same except there will be an additional
print of the GPU that the message has originated from in order to help debug
cases where both an iGPU and dGPU are active. Also the implicit newline
added in the legacy API has been removed. This is inline with essentially
every other print function in the C world. There are numerous places where
'\n' is added despite it not being needed which results in log files being
littered with blank lines. This makes the logs much harder to read.

Split as_gk20a.c into two parts:
common/linux/ioctl_as.c deals with as related devnodes and ioctls.
This file contains all the Linux specific parts of as_gk20a.c.
common/as.c deals with general as_gk20a maintenance and is Linux
independent.

Add nvgpu's own implementation of List APIs
This implementation is needed to remove nvgpu's
dependency on Linux specific list implementation
Define a list node as
struct nvgpu_list_node *node;
Define below common APIs:
nvgpu_init_list_node() - initialize list node
nvgpu_list_add() - add new node to list
nvgpu_list_add_tail() - add new node to end of list
nvgpu_list_del() - delete node from list
nvgpu_list_empty() - check if list is empty
Define below macros to simplify access to list:
nvgpu_list_entry() - convert list node to parent
nvgpu_list_next_entry() - find next entry in list
nvgpu_list_first_entry() - first entry in list
nvgpu_list_for_each_entry() - iterator for list
nvgpu_list_for_each_entry_safe() - deletion safe iterator

In the timers code a macro was using __builtin_return_address(0)
when it should have been using _THIS_IP_.
__builtin_return_address(0) will cause the timers code to print
the return address of the function that calls the timers code. This
isn't actually useful, of course. A user actually cares about where
the timers code call comes from which is easily obtained with
_THIS_IP_.

In gk20a_suspend_all_sms(), we currently loop
over all GPCs and then loop over all TPCs in inner
loop
But this is incorrect and leads to SM with
invalid GPC,TPC ids
Fix this by looping over number of TPCs in each
GPC in inner loop
Also, fix gk20a_gr_wait_for_sm_lock_down() as
per below
- we right now wait infinitely for SM to lock down
- restrict this wait with a timeout on silicon
platforms
- return ETIMEDOUT instead of EAGAIN
- add more debug prints with additional data
for SM lock down failures

Implement kmem abstraction and tracking in nvgpu. The abstraction
helps move nvgpu's core code away from being Linux dependent and
allows kmem allocation tracking to be done for Linux and any other
OS supported by nvgpu.

Change nvgpu_kalloc() to nvgpu_big_[mz]alloc(). This is necessary
since the natural free function name for this is nvgpu_kfree() but
that conflicts with nvgpu_k[mz]alloc() (implemented in a subsequent
patch).
This API exists becasue not all allocation sizes can be determined
at compile time and in some cases sizes may vary across the system
page size. Thus always using kmalloc() could lead to OOM errors due
to fragmentation. But always using vmalloc() is wastful of memory
for small allocations. This API tries to alleviate those problems.

In two places we used broadcast register as base, but added the
unicast offset to it. This causes the write to go well beyond
valid register range.
Change the broadcast base to use unicast base instead in sequence
to resume a single SM and to record error state of SM.

Most of BIOS parsing code is not specific to any particular GPU. Move
most of the code to generic files, and leave only chip specific parts
dealing with microcontroller boot into chip specific files.
As most of the parsing is generic, they do not need to be called via
HALs so remove the HALs and change the calls into direct function
calls.
All definitions meant to be used outside BIOS code itself are now in
<nvgpu/bios.h>
