Add a PHY configuration sequence for the sc8280xp which uses a Qualcomm
Gen 2 version 1.1 CSI-2 PHY.

The PHY can be configured as two phase or three phase in C-PHY or D-PHY
mode. This configuration supports two-phase D-PHY mode.

Aside from initialization, looks like the reset seq should be more
complex:

similarly for the "common regs" that seem to extend the init seq
