[PATCH RFC 2/4] drm/nouveau/dp: Use the generic helper to control LTTPR transparent mode

[Abel Vesa]

LTTPRs operating modes are defined by the DisplayPort standard and the
generic framework now provides a helper to switch between them.
So use the drm generic helper instead as it makes the code a bit cleaner.
