drm/i915: Software workaround for getting the HW status of DSI Port C on BYT
Due to hardware limitations on BYT, MIPI Port C DPI Enable bit
does not get set. To check whether DSI Port C was enabled in BIOS,
check the Pipe B enable bit for DSI Port C. In hardware, DSI Port C
is linked with Pipe B.
v2: Addressed review comments of Jani, Nikula
- Used platform checks for this software workaround for BYT
