MIPS: Loongson: Cleanup machtype support
To choose code for different machines by the value of machtype it needs to be initialized as early as possible. So move initialization of mips_machtype to prom_init(). Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Cc: linux-mips@linux-mips.org Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
