drm: panel-backlight-quirks: Make EDID match optional
[ Upstream commit 9931e4be11f2129a20ffd908bc364598a63016f8 ]
Currently, having a valid panel_id match is required to use the quirk
system. For certain devices, we know that all SKUs need a certain quirk.
Therefore, allow not specifying ident by only checking for a match
if panel_id is non-zero.
