msm: kgsl: always check ft and hw gates in kgsl_active_count_get

The device state can fluctuate during recovery and resume, so
it is safer to check the gates unconditionally rather than
trust the state. The gates are left open until recovery
or suspend starts.

msm: kgsl: Do not wait for FT gate in fault tolerance state

When device start fails, device is in INIT state and FT is triggered.
In FT we trigger snapshot which waits on ft_gate when active count is
0 and device is not in active state. This causes a deadlock. This
change does not wait for FT gate in FT state and thereby prevents
the deadlock.

msm: kgsl: enable CPU IRQ while suspending context

Make sure that CPU interrupt is enabled before calling adreno
suspend_context when moving from NAP/SLEEP to SLUMBER state.
We send commands to GPU in adreno_drawctxt_switch() which will generate
GPU interrupt. Since CPU interrupt is not enabled, adreno_idle() will
fail because pending interrupt will not be served by CPU this causes
false GPU hang.

Execute shader on wakeup from power collapse

After wakeup from power-collapse, a shader execution is needed
to reset the GPU to a known and stable state on certain targets.
This change implements the required shader execution only
on initialization and on recovery from power-collapse on A3xx
GPU targets.
