[arshadm78]

Celadon Failed to boot to GUI on CherryTrail/CherryHill platform.

Observations:
Kernel boots fine to console with no crash reported. kernel version 4.19.46
i915 initializes successfully.
Android logo visible but stuck after some time
HWC keep giving errors
iahwcomposer: CommitFrame: Failed to commit pset ret=Unknown error -22
iahwcomposer: Commit: Failed to Commit layers.

Attached are logcat and dmesg logs from successful boot on KBL and failed boot on CHT for comparison.

Thanks,
Arshad
