drm/edid: index CEA/HDMI mode tables using the VIC
Add a dummy entry to CEA/HDMI mode tables so they can be indexed
directly using the VIC, avoiding a +1/-1 dance here and there. This adds
clarity to the error checking for various functions that return the VIC
on success and zero on failure; we can now explicitly check for 0
instead of just subtracting one from an unsigned type.
Also add drm_valid_cea_vic() and drm_valid_hdmi_vic() helpers for
checking valid VICs.
v2: add drm_valid_cea_vic and drm_valid_hdmi_vic helpers (Ville)
use { } instead of { 0 } for initializing the dummy modes
