msm: kgsl: GPU fault tolerance timer

GPU fault tolerance timer with a 50ms interval is introduced to detect
the condition where GPU is stalled, when GPU state is active we check
for GPU stall and if a stall is detected fault tolerance is triggered.
Using a timer is a better design because this removes dependency
on userspace to call waittimestamp.

msm: kgsl: Check long IB only for valid context

Do not check for long IB if the hang is detected in a NULL context,
hang in NULL context can happen when we are switching from NULL to
active context and hang is detected in commands that write an
active context to memstore, long IB in this scenario is not possible.

msm: kgsl: Set alignment to 0 when low on mapped memory

If CPU map returns error due to low memory then we need to set
the alignment to 0 and instead of setting it to PAGE_OFFSET. This
is because we then simply search of a free memory gap at page
boundary and disrerard alignment requirement since memory is
low.

Fence sync seems to react badly when it gets a unexpected timestamp

even if the event expired because the context was destroyed.

msm: display: Handle mixer stage commit for wfd correctly

If no dequeue buffer is present, do not return early as commit

Early return of commit, results in pipe still staged errors since,
mixer stage and commit gets bypass.

msm: kgsl: Configure FT behaviour from sysfs instead of debugfs

FT behaviour is changed to be configured from sysfs
instead of debugfs. Sysfs control gives us the advantage
of configuring FT at bootup and also across bootups.
Persistant configuration across bootups helps
testing by configuring FT once and testing the FT
config across bootups.
