MLK-18163-1: drm: edid: fix HDMI2.0 deep color depth parsing 

The drm_parse_ycbcr420_deep_color_info() is called only for HDMI 2.0,
however the DC masks were incorrectly set. These were set according
to HDMI 1.4 specification.

This patch will set the deep color depth masks to the HDMI 2.x specs
(see Table 10-6 in HDMI 2.x specs for field descriptions).
