Patch 1 records whether a CSIPHY endpoint is D-PHY or C-PHY from its device-tree bus-type property (instead of rejecting anything that isn't D-PHY), storing it in struct csiphy_lanes_cfg. Patch 2 threads that PHY type through to link-frequency calculation: camss_get_link_freq() gains a cphy parameter and scales its per-lane divisor to match C-PHY's 16-bits-per-7-symbols encoding (vs. D-PHY's 1 bit/symbol), and the CSID gen3 RX front-end's CSI2_RX_CFG0 register is programmed with the matching PHY_TYPE_SEL bit so C-PHY streams are actually decoded as C-PHY instead of silently defaulting to D-PHY.
