msm: kgsl: Set sysfs max clock for devices with no power scale policy

When the sysfs entry for max clock is updated, set it immediately for the
devices that has no power scale policy. This prevents the device from
running with undesired clock.

msm: kgsl: Restore the value of RB_BC_CONTROL on context switch

On 8x25Q, when GPU footswitch is turned off during TCXO shutdown, the
RB_BC_CONTROL register value is lost which causes GPU hang after coming
out of TCXO shutdown. Now the value of RB_BC_CONTROL is preserved properly
during context save and restore.

msm: kgsl: Calculate busy interval considering GPU freq as float

GPU freq could be non-integral value and treating it as an integer
to calculate GPU busy insterval leads to higher busy interval
and more often we see negative idle stats. This change caculates
busy interval by treating gpu freq to the correct precision.

msm: kgsl: Hold the pm_qos vote at all times when ACTIVE

The GPU needs access to the L2 cache while running.  If the
CPU is not also active using the cache can lead to stability
issues.  Keep the CPU out of idle power collapse at all times
while the GPU is running.

msm: kgsl: Use the correct units for ADRENO_IDLE_TIMEOUT

In a few spots the ADRENO_IDLE_TIMEOUT value (measured in milliseconds)
was used directly for jiffy calculations resulting in timeouts that were
1000/HZ times longer than they should have been.  Use msecs_to_jiffies
for these situations.

msm: kgsl: Turn off the CP_DEBUG dynamic clock

The CP dynamic clock seems to be glitchy when the CP clocks are turned
back on after a power event. Turn off said dynamic clock control at
init time. The impact of leaving the dynamic clock control off is
negligible since the CP clock is only on when the CP is actually in
use.

msm: kgsl: Add CP_WAIT_FOR_IDLE packet before updating timestamp

HW workaround to resolve MMU pagefault caused by memory
freeing early before GPU completes it.

This is race condition where timestamp is getting updated
and the event handler runs before the GPU actually got done
with the timestamp, hence freeing the buffer early while GPU
still not completed with it.

msm: kgsl: Always submit an interrupt request to the GPU

A context does not have to be present to send an internal dummy
command to the GPU.  Remove BUG() in this case and instead send
a NULL context which will still cause the interrupt to get submitted
to the GPU.

This reverts commit f0d1c9b79e05972816b92bd43b29e98f764826ea.

Reverting this change since it corrupts Bin Base Offset between
