ENGR00134274 - EPDC fb: Optimize update flow by merging compatible updates
- Created a worker thread to centralize all update requests (new and collisions)
- Added routine to merge compatible updates
- Separated PXP processing from update ioctl and ISR flows into workqueue flow
- Added IOCTL to turn control the update scheme. Supported schemes
are snapshot mode (the old update scheme), queued mode, and queued mode
with combining.
- Added collision-handling refinement based on update submission order
- Added support for 8bpp setting from kernel command line option
