Subject: [PATCH RFC 3/4] drm/i915/dp: Use the generic helper to control
LTTPR transparent mode
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.
