powerpc/83xx: add kmcoge5ne board support

This board is a MPC8360 board. Two flashes are present
a NOR flash were u-boot and the u-boot environment is stored
and a NAND flash for the application code. This board has 512MB
SDRAM.

Additionaly we introduce a common km8360.h file and convert kmeter1 to
use this.
