disp: msm: dp: validate edid before dereferencing

Bladeren bron 
Currently, when using custom edid from debugfs, the
extensions data inside the edid block is not validated
before dereferencing the extension block.

The fix adds a edid validation function to validate
any custom edids before accessing any members in the
edid block.
