net: phy: realtek: add support for reading MDIO_MMD_VEND2 regs on RTL8125/RTL8126
RTL8125/RTL8126 don't support MMD access to the internal PHY, but
provide a mechanism to access at least all MDIO_MMD_VEND2 registers.
By exposing this mechanism standard MMD access functions can be used
to access the MDIO_MMD_VEND2 registers.
