[PATCH 1/3] AT91: update at91_eth_data for ETX2-3 on PA10-11

[Tim Barr]

One point of interest, I have checked both Atmel EK designs
(9260 and 9G20) and they both use PA10 and PA11 for EMAC EXT2
and EXT3. Since the EK boards are built to use the RMII version
of the EMAC interface, the pin assignments of PA23 and PA24 in 
the kernel were not much of an issue. But since my design uses
MII for part cost and EMI issues, I have to change the pin
assignments.
