On Icelake, a separate power well PG2 is created for 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) * Fix Comments (Imre)
