MIPS: Loongson: Split the implementation of prom and setup parts
This patch split the old initilization and setup implementation to
several file, one file one logic function.
the other main changes include:
1. as the script/checkpatch.pl suggests, use strict_strtol instead
of simple_strtol in arch/mips/lemote/lm2e/cmdline.c
2. use the existed macros in asm/mips-boards/bonito64.h as the
arguments of set_io_port_base() and remove the un-needed ones in
asm/mach-lemote/pci.h
