pinctrl: renesas: rzg2l: Validate power registers for SD and ETH

Browse source

On RZ/V2H(P) SoC, the power registers for SD and ETH do not exist,
resulting in invalid register offsets.  Ensure that the register offsets
are valid before any read/write operations are performed.  If the power
registers are not available, both SD and ETH will be set to '0'.
