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

We'll be wanting to compute has_hdmi_sink a bit differently
for some platforms. To that end compute it in the encoder
.compute_config_hook() before we call intel_hdmi_compute_config().
intel_hdmi_compute_has_hdmi_sink() will do the basic lifting
beyond any platform specific stuff.
