For PDR, the crashed state should be set to invoke driver's
PDR/SSR routine rather than the remove routine.

Pointer from userspace is de-referenced before the command is checked.
This might cause a crash if the command being sent is not a valid command.
Hence changing the de-reference such that the pointer is accessed after
checking if a valid command is sent from the userspace.

During qseecom driver probing, the ION driver is invoked.
This commit supports the case where the ION driver still hasn't
probed. In that case, the qseecom probing will be deferred, and
retried at a later stage.

The size of the settings, copied from userspace, is directly checked
in msm_cci_data_queue with CCI_I2C_MAX_WRITE. This might cause
out of bound access in function msm_cci_data_queue as the max size is
MAX_I2C_REG_SET. Hence adding check on the size in flash driver itself.

When enabling animation/static splash in LK, drm/kms driver needs
to involve handoff code to support smooth transition. In display
driver's probe, it will do following items:
1. Check the status in LK for early splash.
2. Add data bus bandwidth voting in function sde_splash_init.
2. Handle SMMU mapping issue to avoid SMMU fault problem.
3. Bypass hardware reset to avoid glitch.
And after user's space is up, when first commit's vblank comes,
it will call functions to:
1. Tell LK to stop static/animation display and to exit.
2. Set early_domain_map_attr to 1 to enable stage 1 translation in
iommu driver.
3. Check the property of commit.If it's for HDMI, release HDMI
resource. If for DSI, release DSI resource.
4. Recycle the memory to be available to system.
5. Withdraw the bus bandwidth voting.

The generic msm_gpu_pm_resume/msm_gpu_pm_suspend functions have
built-in reference counting but the a5xx specific functions
are doing unconditional a5xx specific setup / teardown that
would behave very badly if they were not accompanied by an
actual power up / power down.

We should have a corresponding syncpoint_fence trace
for every syncpoint_fence_expire trace. In case the
fence is already signaled then make sure to have
syncpoint_fence trace before syncpoint_fence_expire
trace.
Also take an extra refcount for fence which will make
sure that the fence pointer is valid in the trace even
if the fence is signaled.
