[Intel-gfx] [PATCH 3/6] drm/i915: Move platform checks into intel_hdmi_bpc_possible()

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Let's put the platform checks into intel_hdmi_bpc_possible() so that
it'll confirm both the source and sink capabilities.
