[U-Boot] [PATCH v2] net: phy: marvell: Add functions to read PHY's extended registers

This commit allows extended Marvell registers to be read with:
foo > mdio rx FEC 3.10
Reading from bus FEC
PHY at address 0:
3.16 - 0x1063
foo > mdio wx FEC 3.10 0x1011
The above code changes the way ETH connector LEDs blink.

Changes in v2:
- Provide the readext and writeext callbacks to other marvell ETH PHY
devices
