Log: [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.
