Suraj Kandpal 7f97a0a871 drm/i915/ddi: Guard reg_val against a INVALID_TRANSCODER ...

Currently we check if the encoder is INVALID or -1 and throw a
WARN_ON but we still end up writing the temp value which will
overflow and corrupt the whole programmed value.

--v2
-Assign a bogus transcoder to master in case we get a INVALID
TRANSCODER [Jani]

Fixes: 6671c367a9 ("drm/i915/tgl: Select master transcoder for MST stream")
