MIPS: Loongson: clean up the coding style
With the help of script/checkpatch.pl, i have cleaned up the coding style. 1. remove un-needed header files and tune some comments. 2. remove some un-needed { } add a new header file loongson.h: 3. move some common header files to loongson.h 4. move some common extern declartions to loongson.h and this new header file is needed for future loongson2f support. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
