If there had no any pipe blending stage changes, then do not
call belnding set up to avoid unnecessary warning messges.

msm_fb: display: exit properly when rotator max session reached

When rotator session reach maximum, it should exit without calling
put_img since no get_img had been called.

msm_fb: Fix adb shell start/stop issue when bypass enabled

Currently when 2/3/4 layer bypass is enabled, doing a adb shell
stop/start is failing overlay and composition happens through
GPU. Fix this issue by proper overlay configuration during this
scenario.

msm: kgsl: Resolve a potential race in the interrupt handler

In the GPU interrupt handler we attempt to clear the ts_cmp_enable
for the active context so that future interrupts are skipped until
someone needs one again. If for some reason the interrupt handler
is delayed then there is a possiblity that the "current" context in
the GPU isn't the one that fired the interrupt. In that case we
could be accidently clearing a ts_cmp_enable for a context that
needs it. Instead of clearing in the interrupt handler clear it
from the GPU so we can be sure we got the right context.

As a bonus pushing this logic to the GPU side lets us get rid of
some extra register reads/writes in the interrupt handlers.

msm: kgsl: Check the current interrupt status before power operations

Sometimes the core will go idle before the interrupt can be handled on
the GPU. If that happens then we could go to a lower power state before
cleaning up the pending interrupt and various entities that might be
waiting for it. Consider the current interrupt status when checking
for idle.
