powerpc/83xx: rename and update kmeter1

Beside the MPC 8360 based board kmeter1 other km83xx boards
from keymile will follow. Therefore the board specific naming
kmeter1 for functions and files were replaced with km83xx.
Additionally some updates were made:
    - update defconfig for 2.6.38
    - rework flash partitioning in dts file
    - add gpio controller for qe_pio_c in dts
