drm/i915/fbc: Introduce device info fbc_mask
Declare which FBC instances are present via a fbc_mask
in device info. For the moment there is just the one.
TODO: Need to figure out how to expose multiple FBC
instances in debugs. Just different file names, or move
the files under some subdirectory (per-crtc maybe), or
something else? This will need igt changes as well.
v2: Put the mask into device_info.display (Jani)
Put the magic pipe->fbc thing into skl_fbc_id_for_pipe() (Jani)
