mb/google/corsola: Add support for MIPI panel

The detachable Starmie will use MIPI panels, which require reading
serializable data from the CBFS. So we add MIPI panel support to the
display configuration and align the configuration sequence with the
panels that use MIPI bridges.

The PMIC Datasheet:
