[U-Boot] [PATCH V2 RESEND 14/24] SPEAr: Enable autoneg for ethernet

From: Shiraz Hashim <shiraz.hashim at st.com>

Enabling autoneg avoids situation on few phys with fixed configuration. For
example, in one situation, nfs boot timed out when phy configuration is 100Mbps.
In another situtation, when traffic is directed to SPEAr, either thru
cross-cable or thru switch, the TFTP or DHCP command in u-boot starts to timeout
very often.

When Autoneg is ON, same phys started working perfectly.
