drm/i915: Extract intel_bw_update_hw_state()

Browse Source 
Hoist the bw stuff into a separate function from
intel_modeset_readout_hw_state() so that the details
are better hidden inside intel_bw.c.

We can also skip the whole thing on pre-skl since the dbuf state
isn't actually used on those platforms.
