drm/edid: Add a function to match EDID with identity

Create a type drm_edid_ident as the identity of an EDID. Currently it
contains panel id and monitor name.

Create a function that can match a given EDID and an identity:
1. Reject if the panel id doesn't match.
2. If name is not null in identity, try to match it in the detailed timing
   blocks. Note that some panel vendors put the monitor name after
   EDID_DETAIL_MONITOR_STRING.
