[CI v2] drm/i915/dp: Dump the LTTPR PHY descriptors

[Imre Deak]

Dump the descriptor of the detected LTTPRs in non-transparent mode to
help the debugging related to LTTPRs easier.

v2: Use drm_dp_dump_lttpr_desc() instead of the driver specific
    equivalent.
v3: Add empty line between license and header section. (Ankit)
v4: Don't include drm_dp_helper.h twice. (Jani)
