[PATCH v1 1/1] drm: drop unused drm_display_mode.private

[Sam Ravnborg <sam@ravnborg.org>]

drm_display_mode.private was only referenced in one place where
is was copied but never assigned.

Drop the copy and drop the field in drm_display_mode.
Adjust the comment of private_flags as is referred to the comment for
private.

Again, something I just stumbled upon.
I also checked private_flags - it is used in a few modules.
And it looked legit.

Build tested with allmodconfig, allyesconfig, allnoconfig for relevant
architectures.
