net: phy/realtek: Add support for RTL8211DN and RTL8211E phy modules
This patch adds support for Realtek PHY modules RTL8211DN and RTL8211E (variants: RTL8211E-VB-CG, RTL8211E-VL-CG, RTL8211EG-VB-CG), which can be found on Freescale's T1040RDB boards. To make the driver more generic across 8211 family, a generic name 8211x is added for macros and function names.
