imx-drm updates

- atomic mode setting conversion
- replace DMFC FIFO allocation mechanism with a fixed allocation
  that is good enough for all cases
- support for external bridges connected to parallel-display
- improved error handling in imx-ldb, imx-tve, and parallel-display
- some code cleanup in imx-tve
