Add setup for ethernet on SMDKC100, allowing kernel/ramdisk to be loaded over tftp.

The preinit function will configure GPIO (GPK0CON) & SROMC to look for environment in SROM Bank 3.

Signed-off-by: Naveen Krishna Ch ch.naveen@samsung.com

Changes since V1:

1. The CONFIG_BOOTP* and Net config Macros are removed from config header.

Comments from Ben Warren are fixed 2. The GPIO configuration is modified & Macro and Function are renamed. Comments from Minkyu Kang are fixedChanges since V2

Changes since V2:

1. GPIO configurations function has been implemented.
