drm/panel: Changes for v4.2-rc1

This contains fixes for the long-standing build issues that some of the
bridge drivers were exposing. Other than that it's mostly cleanup and a
couple of new simple panels that are supported.

  drm/panel: simple: Add bus format for HannStar HSD100PXN1
  drm/panel: simple: Add display timing for HannStar HSD100PXN1
  drm/panel: ld9040: Remove useless padding
  drm/panel: Constify OF match tables
  drm/bridge: Remove stale ptn3460.h include
  drm/bridge: ps8622: Include linux/gpio/consumer.h
