[U-Boot] [PATCH] [U-BOOT] Zoom2: Ethernet: Enabling LAN9221 chip and CMD_NET.

[Aldo Brett Cedillo Martinez]

Configures GPMC, adds macros to enable net commands, and adds proper
initialization to board_eth_init function.

I have a similar patch to enable ethernet in zoom3 after initial support
patch.
