ppc4xx: netstal/common define routines used by all boards

Browse Source 
Added some routines used by all Netstal boards:
- nm_bsp.c: - nm_show_print and
        -  common_misc_init_r
        - set_params_for_sw_install. Very specific code to handle our SW
          installation procedure
- fixed_sdram.c: Common routines for HCU4 (and upcoming) MCU25 boards
  to handle sdram initialization.
- nm.h: Common header
