lib/kms: Add universal plane support (v2)
Add support for universal planes. This involves revamping the existing
plane handling a bit to allow primary & cursor planes to come from the
DRM plane list, rather than always being manually added.
v2: Don't drop fixed ordering of internal plane list. Primary will
always be index 0, cursor will always be last in internal plane
list.
