[Intel-gfx] [PATCH 3/4] drm/i915/display: Replace intel_dp_set_infoframes() enable calls by dig_port->set_infoframes()

["José Roberto de Souza" <jose.souza@intel.com>]

intel_dp_set_infoframes() and set_infoframes() hook had some code
overlapping that makes sense us try to drop it.

set_infoframes() is called during the pre_enable phase while
intel_dp_set_infoframes() was being called in the enable phase but
it was only enabling DP_SDP_VSC and HDMI_PACKET_TYPE_GAMUT_METADATA
infoframes, that were added back to hsw_set_infoframes() and
lspcon_set_infoframes().

Did not found any information about why this difference of phase but
if it is not supported our CI will probably catch it.

As hsw_set_infoframes() will now be called during the fastset updates
the assert_hdmi_transcoder_func_disabled() check needed to be dropped.
