Re: [U-Boot] [PATCH u-boot] net: phy: realtek: Add functions to read PHY's extended registers

According to the datasheet to access the extended registers we have to:

1. Write Register 31 Data = 0x0XYZ (Page 0xXYZ)
2. Read/Write the target Register Data
3. Write Register 31 Data = 0x0000 or 0xa42 (switch back to IEEE Standard Registers)

Hook the missing functions so that we can use the `mdio rx/wx` command to easily access the extended registers.
