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.

Move TSG IOCTL specific code to Linux module. This clears most
Linux dependencies from tsg_gk20a.c.
Move also remaining file_operations declarations from channel_gk20a.h
to ioctl_channel.h.

Add abstractions for the following:
msleep()
udelay()
usleep_range()
These functions are only a subset of the available Linux delay and sleep
functions but this seems to be what we use and what is actually useful
for driver development.

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.

Remove an 0x that prepended a function name print (not a
function address so the 0x is pretty silly).

The Linux timer code prints an error message containing the caller when
a timeout happens. The caller is formatted as a function name instead of
a pointer, so don't print 0x in front of it.

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.

Instead of using a single static kmem_cache for each type of
data structure the allocators may want to allocate each
allocator now has its own instance of the kmem_cache. This is
done so that each GPU driver instance can accurately track how
much memory it is using.
In order to support this on older kernels a new NVGPU API has
been made,
nvgpu_kmem_cache_create(struct gk20a *g, size_t size)
To handle the possibility that caches cannot be created with
the same name.
This patch also fixes numerous places where kfree() was wrongly
used to free kmem_cache allocs.

Change "check" to "expired" in nvgpu_timeout_check* and append _expired
to nvgpu_timeout_peek to clarify what the boolean-like return value
means and thus avoid bugs.

Add a timeout API to nvgpu since this is a common operation done all
across the nvgpu driver.
Also add two new directories for this common code:
drivers/gpu/nvgpu/common
drivers/gpu/nvgpu/include/nvgpu
The common directory is for common C code. The include directory is for
common include files.
