drm-misc-next for v5.6:

UAPI Changes:

Cross-subsystem Changes:
- Convert simple panel bindings to a template.

Core Changes:
- Revert drm-bridge-state changes, it causes a dependency error
  between drm and drm_kms_helper.
- Fix when disabling crc's.
- Assorted Kconfig fixes.

Driver Changes:
- Add ddc symlinks to more drivers.
- Fix chained bridge handling in exynos and vc4.
- More clock rate fixes in sun4i.
- Add support for AUO B116XAK01, GiantPlus GPM940B0, Sony ACX424AKP,
  BOE NV140FHM-N49, Satoz SAT050AT40H12R2 and Sharp LS020B1DD01D panels.
