Prep patches + headers for the mei-hdcp/i915 component interfaces

Also contains the prep work in the component helpers plus adjustements
for the snd-hda/i915 component interface.

Plus one small static inline in the drm_hdcp.h header that both i915
and mei_hdcp will need.

drm/i915 fixes for v5.0-rc7:
- combo phy programming fix
- opregion version check fix for VBT RVDA lookup
- gem mmap ioctl race fix
- fbdev hpd during suspend fix
- array size bounds check fix in pmu

typed componented support + i915/snd-hda changes

This is needed by the new MEI-HDCP support in i915, so will need to go
in through drm and drivers-misc trees at least.
