Ack.

Whoops, this one was an accident.

However this one was intentional. So the register isn't "an fbc
register", but the contents are all about fbc, and it's only used in
intel_fbc.c.

I guess after all reasonable topical things have been split out from
i915_reg.h, whatever display stuff is left will need to be put to a new
intel_display_regs.h or something. Things like this would then end up
there. Better or worse that way, I don't know.

BR,
Jani.
