drm/i915: Add state readout for DRM infoframe 



Added state readout for DRM infoframe and enabled
state validation for DRM infoframe.

v2: Addressed Ville's review comments and dropped the
unused drm infoframe read at intel_hdmi_init.

v3: Removed a redundant platform check as per Ville's
comment.
