keystone2: net: add keystone ethernet driver
Ethernet driver configures the CPSW, SGMI and Phy and uses the the Navigator APIs. The driver supports 4 Ethernet ports and can work with only one port at a time. Port configurations are defined in board.c. Signed-off-by: Vitaly Andrianov <vitalya@ti.com> Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: WingMan Kwok <w-kwok2@ti.com>
