Subject: [PATCH 3/6] media: qcom: camss: csiphy-3ph: Add Gen2 v1.2.2
 two-phase MIPI CSI-2 DPHY init

From: George Chan <gchan9527@...il.com>

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.
