[PATCH v4 03/27] drm/amd/display: Remove redundant edid checks

[Tomasz Pakuła]

[Why]
Edid parsing functions check if edid is not null themselves. In a case
where edid is not present, the structs will be left initialised to 0
so anu possible assigment won't change the detected (or undetected)
functionality.

[How]
Remove edid pointer checks
