From: George Chan <gchan9527@xxxxxxxxx>

Add a PHY configuration sequence for the sc7180 which uses a Qualcomm
Gen 2 version 1.2.2 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.

This is the init sequence for 1_2_1 not 1_2_2
