drm/amd/display: Lock DC and exit IPS when changing backlight
Backlight updates require aux and/or register access. Therefore, driver
needs to disallow IPS beforehand.
So, acquire the dc lock before calling into dc to update backlight - we
should be doing this regardless of IPS. Then, while the lock is held,
disallow IPS before calling into dc, then allow IPS afterwards (if it
was previously allowed).
