drm/i915: Switch to LTTPR transparent mode link training
By default LTTPRs should be in transparent link training mode,
nevertheless in this patch we switch to this default mode explicitly.
The DP Standard recommends this, supposedly because an LTTPR may be left
in the non-transparent mode (by BIOS, previous kernel, or after reset
due to a firmware bug). I haven't seen this happening, but let's follow
the DP Standard.
v2:
- Add a code comment about the explicit disabling of non-transparent
mode.
v3:
- Move check to prevent initing LTTPRs on eDP to init_dp_lttpr_init().
