drm/i915/icl: fix transcoder state readout
Commit 2ca711caeca2 ("drm/i915/icl: Consider DSI for getting transcoder
state") clobbers the previously read TRANS_DDI_FUNC_CTL_EDP register
contents with TRANS_DDI_FUNC_CTL_DSI0 contents. Fix the state readout,
and handle DSI 1 while at it.
Use a bitmask for iterating and logging transcoders, because the allowed
combinations are a bit funky.
