arm, ppc: rework environment variables for keymile boards
This patch reworks all headerfiles for keymile boards. Furthermore
the environment variables are refactored.
Changes:
- introduce km-powerpc.h file and extract ppc specific parts to it
- move ARM specific options and vaiables to km_arm.h
- sort the environment variables to logical groups
- enhance the description of the environment variables
- remove KM specific HW key and board id from kernel command line
