drm/i915/ddi: split up intel_ddi_read_func_ctl() by output type

Browse source

The function has become quite long, and the switch-case statement quite
complex with the fallthrougs. Simplify by splitting to individual
functions and an if-ladder.

This highlights how TRANS_DDI_MODE_SELECT_FDI_OR_128B132B works on
different platforms.
