[PATCH RFC 3/4] media: qcom: camss: csid-680: Select C-PHY in the receiver

[George Neacsu via B4 Relay]

From: George Neacsu <geocausa@xxxxxxxxx>

CSID 680 has a PHY type select in CSI2_RX_CFG0, next to the PHY number.
The field is defined but never written, so the receiver always decodes
D-PHY. Write phy_sel to it, as csid-gen2 does for C-PHY.
