drm: add plane support v3

Browse Source 
Planes are a bit like half-CRTCs.  They have a location and fb, but
don't drive outputs directly.  Add support for handling them to the core
KMS code.

v2: fix ABI of get_plane - move format_type_ptr to the end
v3: add 'flags' field for interlaced support (from Ville)
