lib/kms: Add universal plane support (v2)

Browse Source 
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.
