Subject: drm/edid: Clear EDID Deep Color Modes in drm_reset_display_info()
MIME-Version: 1.0

Git-commit: 70c0b80d0bbb97c072c4a9c3e8b0f68a9e22d7d2
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

Even though we have the other drm_display_info fields reset, the DC
modes are missing.

This shouldn't be an issue since it's explicitly reset every time a new
EDID is parsed.
