[PATCH v2 1/5] drm: panel-backlight-quirks: Make EDID match optional

[Antheas Kapenekakis <lkml@antheas.dev>]

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.
