drm/i915/bw: Relocate intel_bw_crtc_min_cdclk()

Browse source 
intel_bw_crtc_min_cdclk() (aka. the thing that deals with what bspec
calls "Maximum Pipe Read Bandwidth") doesn't really have anything to
do with the rest of intel_bw.c (which is all about SAGV/QGV and
memory bandwidth). Move it into intel_crtc.c (for the lack of a better
place).

And I don't really want to call intel_bw.c functions from intel_crtc.c,
so move out intel_bw_crtc_data_rate() as well. And when we move that we
pretty much have to move intel_bw_crtc_num_active_planes() as well since
the two are meant to be used as a pair (they both implement the same
"ignore the cursor" logic).

And in an effort to keep the namespaces at least semi-sensible we
flip the intel_bw_crtc_ prefix into intel_crtc_bw_.
