arm64: dts: qcom: sdm630: order regs according to bindings

The CAMSS DTSI device node, which came after the bindings were merged,
got the regs ordered differently then specified in the bindings:

  sdm636-sony-xperia-ganges-mermaid.dtb: camss@ca00000: reg-names:0: 'csi_clk_mux' was expected

Reordering them to match bindings should not cause ABI issues, because
the driver relies on names, not ordering.
