gma irl: Handle Ibex Peak DP correctly
We missed some bits specific to Ibex Peak DPs. Namely, the training pattern selection moved and we have to select the transcoder in the `DP_CTL` register as there is no separate DP transcoder register.
The latter is quirky, however. If a port (DP or HDMI) is disabled with the second transcoder selected. This selection sticks and the sibling port (e.g. DP2 to HDMI2) can't be enabled with the first transcoder. As a workaround, we are supposed to enable a port that was using the second transcoder with the first transcoder selected again.
