Added support for K2G EVM with FlipChip SoC of which ARM/DDR3 runs at 1GHz/1066 MT/s. The patch is also backward compatible with old revision EVM and EVM with WireBond SoC. Their ARM/DDR3 run at 600MHz/800 MT/s.
The new SoC supports 2 different speeds at 1GHz and 600MHz. Modyfied the CPU Name to show which SoC is used in the EVM. Modified the DDR3 configuration to reflect New SoC supports 2 different CPU and DDR3 speeds, 1GHz/1066MT and 600MHz/800MT.
Added new inline function board_it_k2g_g1() for the new FlipChip 1GHz, and set the u-boot env variable board_name accordingly.
Modified findfdt script in u-boot environment variable to include new k2g board type.

Lets not ifdef around externs.

Yeah, basically both are rev 1.0 but with different speed grades. This is the naming convention recommended from marketing team.
