Michael Zhilin 334453c5a9 [nvram2env] split implementation into generic & MIPS-based code
Split implementation of nvram2env to generic (MI) & MIPS-based code:

 - removed includes like "*siba*", because they are unused
 - added nvram2env_mips.c file with MIPS-specific code, code moved from nvram2env.c
 - added header file to shared defines/structures/function prototypes between MI and MIPS code

Also this fix allows to implement own nvram2env drivers.
