From: José Roberto de Souza <jose.souza@xxxxxxxxx> Tiger Lake has up to 4 pipes so the mask would need to be 0xf instead of 0x7. Do not hardcode the mask so it allows the fake MST encoders to connect to all pipes no matter how many the platform has. Iterating over all pipes to keep consistent with intel_ddi_init().
