Support the mac3 (RGMII4) as an NC-SI stack instead of an MDIO PHY.
The OCP slot #0 and OCP slot #1 use a common the BMC_NCSI signal,
so we use only one of them at the same time. The OCP slot #0 will
be enabled by PCA9539's setting by default.
Also, enable the OCP Auxiliary Power during booting.

Node names should be generic, so I believe this is "gpio".

Thank Krzysztof,
The PCA9539APW is a GPIO expander via I2C. For a generic name, I think
the "gpio" is suitable.
