[PATCH 1/3] arm64: dts: qcom: lemans: add CSI2 D-PHY common-phy providers

[Anusha Arun Nandi]

Expose the four SA8775p CSIPHYs as standalone qcom,sa8775p-csi2-phy
generic-PHY provider nodes (csiphy0..3) at their existing register
addresses, each with its own OF graph (port@0 sensor-facing, port@1
CAMSS-facing) so camss_detect_legacy_phy() picks the non-legacy path
once a board wires a sensor through one of them. The camss node's own
reg-names/clocks/interrupts for the CSIPHYs are unchanged, so boards
that don't use a provider still get the legacy binding.

The provider nodes are disabled by default; a board or camera overlay
enables the one(s) it uses.
