Merge tag 'drm-intel-next-2021-04-01' of git://anongit.freedesktop.org/drm/drm-intel into drm-next

Features:
- Add support for FBs requiring a power-of-two stride padding (Imre)

Refactoring:
- Disassociate display version from gen (Matt)
- Refactor legacy DP and HDMI code to separate files (Ville)
- Refactor FB plane code to a separate file (Imre)
- Refactor VBT child device info parsing and usage (Jani)
- Refactor KBL/TGL/ADL-S display and gt stepping schemes (Jani)

Fixes:
- DP Link-Training Tunable PHY Repeaters (LTTPR) fixes (Imre)
- HDCP fixes (Anshuman)
- DP 2.0 HDMI 2.1 PCON Fixed Rate Link (FRL) fixes (Ankit)
- Set HDA link parameters in driver (Kai)
- Fix enabled_planes bitmask (Ville)
- Fix transposed arguments to skl_plane_wm_level() (Ville)
- Stop adding planes to the commit needlessly (Ville)
