Add support for CDE scatter buffers. When the bus addresses for
surfaces are not contiguous as seen by the GPU (e.g., when SMMU is
bypassed), CDE swizzling needs additional per-page information. This
information is populated in a scatter buffer when required.

Implement per-channel watchdog/timer as per below rules :
- start the timer while submitting first job on channel or if
no timer is already running
- cancel the timer when job completes
- re-start the timer if there is any incomplete job left
in the channel's queue
- trigger appropriate recovery method as part of timeout
handling mechanism
Handle the timeout as per below :
- get timed out channel, and job data
- disable activity on all engines
- check if fence is really pending
- get information on failing engine
- if no engine is failing, just abort the channel
- if engine is failing, trigger the recovery
Also, add flag "ch_wdt_enabled" to enable/disable channel
watchdog mechanism. Watchdog can also be disabled using
global flag "timeouts_enabled"
Set the watchdog time to be 5s using macro
NVGPU_CHANNEL_WATCHDOG_DEFAULT_TIMEOUT_MS

Add batch support for mapping and unmapping. Batching essentially
helps transform some per-map/unmap overhead to per-batch overhead,
namely gk20a_busy()/gk20a_idle() calls, GPU L2 flushes, and GPU TLB
invalidates. Batching with size 64 has been measured to yield >20x
speed-up in low-level fixed-address mapping microbenchmarks.

Add reference counting for channels, and wait for reference count to
get to 0 in gk20a_channel_free() before actually freeing the channel.
Also, change free channel tracking a bit by employing a list of free
channels, which simplifies the procedure of finding available channels
with reference counting.
Each use of a channel must have a reference taken before use or held
by the caller. Taking a reference of a wild channel pointer may fail, if
the channel is either not opened or in a process of being closed. Also,
add safeguards for protecting accidental use of closed channels,
specifically, by setting ch->g = NULL in channel free. This will make it
obvious if freed channel is attempted to be used.
The last user of a channel might be the deferred interrupt handler,
so wait for deferred interrupts to be processed twice in the channel
free procedure: once for providing last notifications to the channel
and once to make sure there are no stale pointers left after referencing
to the channel has been denied.
Finally, fix some races in channel and TSG force reset IOCTL path,
by pausing the channel scheduler in gk20a_fifo_recover_ch() and
gk20a_fifo_recover_tsg(), while the affected engines have been identified,
the appropriate MMU faults triggered, and the MMU faults handled. In this
case, make sure that the MMU fault does not attempt to query the hardware
about the failing channel or TSG ids. This should make channel recovery
more safe also in the regular (i.e., not in the interrupt handler) context.

Add "force_reset" flag to __gk20a_do_idle()
For real world use cases like VPR resizing, we cannot wait
for railgate_delay (which is 500 mS). Hence use CAR reset
for this use case. (this is done via gk20a_do_idle() API
with force_reset = true)
Some of the test cases make use of sysfs "force_idle" and
they expect GPU to be into really railgated state and
not in CAR reset.
Hence when called from sysfs, set force_reset = false.
When global flag "force_reset_in_do_idle" is set, it will
override local flags and force CAR reset case.
This is desired in cases where railgating is not enabled
Also, set force_reset_in_do_idle = false for GM20B since
railgating has been enabled for GM20B

Remove support for gk20a sparse textures. We're using implementation
from user space, so gk20a code is never invoked.
Also removes ref_cnt for PTEs, so we never free PTEs when unmapping
pages, but only at VM delete time.

Follow steps below to config active TPC number:
echo 1 > /sys/devices/platform/host1x/gpu.0/force_idle
echo 0x1/0x2/0x3 > /sys/devices/platform/host1x/gpu.0/tpc_fs_mask
echo 0 > /sys/devices/platform/host1x/gpu.0/force_idle
where,
0x1 : disable TPC1
0x2 : disable TPC0
0x3 : both TPCs active
Also, add API set_gpc_tpc_mask to update the TPCs and call this
API after update to sysfs "tpc_fs_mask"
Once fuses are updated for new TPC settings, we need to
reconfigure GR and golden_image. Hence disable gr->sw_ready
and golden_image_initialized flags.
Also, initialize gr->tpc_count = 0 each time in
gr_gk20a_init_gr_config(), otherwise it goes on adding tpc count
