drm/i915: Extract pipe_mbus_dbox_ctl_update()
We'll be wanting to reprogram the PIPE_MBUS_DBOX_CTL registers
during an upcoming MBUS sanitation stage. Extract the reprogramming
loop into a helper that doesn't depend on the full atomic state
so that it can be reused.
We'll stick to sturct drm_i915_private for now (instead of
struct intel_display) since the rest of the skl wm code does the
same, and we might need to bakport this.
