[Intel-gfx] [PATCH v2 2/4] drm/edid: Check for user aspect ratio input

[Vandana Kannan]

In case user has specified an input for aspect ratio through the property,
then the user space value for PAR would take preference over the value from
CEA mode list.

v2: Thierry's review comments.
	- Modified the comment "Populate..." as per review comments
