TSEC: add config options for VSC8601 RGMII PHY
The Vitesse VSC8601 RGMII PHY has internal delay for both Rx
and Tx clock lines. They are configured using 2 bits in extended
register 0x17.
Therefore CFG_VSC8601_SKEW_TX and CFG_VSC8601_SKEW_RX have
been introduced with valid values 0-3 giving 0.0, 1.4,1.7 and 2.0ns delay.
