One SDM845 board uses cx-supply, which is not allowed by the bindings,
as reported by dtbs_check:
sdm845-samsung-starqltechn.dtb: remoteproc@5c00000 (qcom,sdm845-slpi-pas): Unevaluated properties are not allowed ('cx-supply' was unexpected)
The SDM845 SLPI binding already allows lcx and lmx domains, thus the
cx-supply seems like a fake name for something else, e.g. some
enable pin. The qcom_q6v5_pas.c driver parses cx-supply, so it is an
established ABI, therefore document it for this device only.
