drm/i915/fbc: Move DPFC_CHICKEN programming into intel_fbc_program_workarounds()
Move all DPFC_CHICKEN programming into intel_fbc_program_workarounds().
We already have one thing programmed there, whereas the rest is strewn
about in intel_display_wa_apply() and init_clock_gating(). Since we have
a single place doing all the programming (and it's serialized by the
crtc commits) there should be no danger of rmw races.
Other FBC related workarounds also exist, but those require fiddling
with other registers that may also get programmed from other places,
so we'll need to think harder what to do with those.
