Subject: drm/panel-simple: Update validation warnings for eDP panel
 description
Git-commit: 13aceea56fd5fcf571ac462b83646c6359699c0a
Patch-mainline: v5.15-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

Do not give a warning for the eDP panels if the "bus_format" is
not specified, since most eDP panels can support more than one
bus formats and this can be auto-detected.
Also, update the check to include bpc=10 for the eDP panel.
