drm/i915/fbc: Extract helpers to compute FBC control register values
Declutter the *_fbc_activate() functions by pulling all the
control register value computations into helpers.
I left the enable bit in *_fbc_activate() in the hopes of maybe
using the helpers in the *_fbc_deactivate() paths as well instead
of the current rmw approach. That won't be possible at least
quite yet since we clobber the fbc->params before deactivating
FBC so we could end up changing some of the values live, which
given FBC's lack of/poor double buffering would likely not go
so well.
