The clock-lanes property corresponds to a hardware register field
that is required to be set, in order to enable the CSI clock signal.
The physical lane of the clock signal is not programmable, but only
togglable On or Off, which what BIT(7) of the
CSIPHY_3PH_CMN_CSI_COMMON_CTRLn(5) register controls.
