drm/edid: parse sink information before CEA blocks

CEA-861-F adds ycbcr capability map block, for HDMI 2.0 sinks.
This block contains a map of indexes of CEA modes, which can
support YCBCR 420 output also. To avoid multiple parsing of same
CEA block, let's parse the sink information and get this map, before
parsing CEA modes.

This patch moves the call to drm_add_display_info function, before the
mode parsing block.

V4: Introduced new patch in the series
V5: Move this patch before 4:2:0 parsing patch (ville)
    Added r-b from Ville
