VDSC engine used for eDP/MIPI DSI. This patch adds a new
display power domain for Power well 2.
v3:
* Call it POWER_DOMAIN_TRANSCODER_EDP_VDSC (Ville)
* Move it around TRANSCODER power domain defs (Ville)
v2:
* Fix the power well mismatch CI error (Ville)
* Rename as VDSC_PIPE_A (Imre)
* Fix a whitespace (Anusha)
