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 Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
