keymile: Fix Coding style issues for keymile boards.

- use I/O accessors
  -> For accessing the FPGA therefore a struct km_bec_fpga
     is introduced.
- no longer externs needed
- to defines, that only select functions, don;t assign a
  numeric value
- Codingstyle changes to prevent checkpatch errors/warnings
