Looking at both i915 and nouveau DP drivers, both are setting the first LTTPR (if found) in transparent mode first and then in non-transparent mode, just like the DP v2.0 specification mentions in section 3.6.6.1. Being part of the standard, setting the LTTPR in a specific operation mode can be easily moved in the generic framework. So do that by adding a new helper. Then, the msm DP driver is
