qseecom: Fix failure to go into suspend

When the device tries to go into suspend the freezer process
fails to put the  blocked threads into sleep.
Hence device is failing to go into suspend as the blocked threads
are woken up by suspend signal (and any signal in general).
Replacing wait_event_interruptable() with wait_event_freezable()
allows the freezer process to freeze the blocked threads,
thereby, allowing the device to proceed with going into suspend.

msm_fb: Remove the extra freelist in display_commit

There is an extra freelist call to unmap IOMMU source buffers
in display_commit for LCDC interface. This is causing IOMMU
page faults during boot up on targets with LCDC interfaces.
Remove this extra freelist call.

msm_fb: display: Do a pre-fill to writeback buffers.

When switching mdp operating mode to blt, writeback buffers need
pre-fill. Move the pre-fill code from isr routine to do_blt, where
actual switch to blt mode happens.

msm_fb: display: fix the hang issue caused by solidfill pipe

When mdp pipe solidfill mode is disabled, the staled pipe info is used
to update mdp pipe regs. This caused mdp hang. Since
mdp4_overlay_rgb_setup function already resets solidfill mode, this
patch removes any pipe register updates that are related to disabling
solidfill mode.

msm: rotator: Add proper checks for enabling Fast YUV

For rotator version 2.0 and above, there is support for fast
YUV which gives better rotator performance. However, there are
few constraints related to height under which fast YUV cannot be
enabled when 90 degree rotation is enabled. Make sure
to add proper checks before enabling fast YUV.
