[U-Boot] [PATCH] MIPS: qemu_mips: Fix a build failure caused by missing <asm/unaligned.h>

[Shinya Kuribayashi]

make -C lib_generic/
zlib.c:31:27: error: asm/unaligned.h: No such file or directory
zlib.c: In function 'inflate_fast':
zlib.c:641: warning: implicit declaration of function 'get_unaligned'
make[1]: *** [zlib.o] Error 1
make[1]: Leaving directory `/home/skuribay/git/u-boot.git/lib_generic'
make: *** [lib_generic/libgeneric.a] Error 2

Import relevant header file from LMO tree (slightly modified to U-Boot).

This is another topic, let's ignore here.

I confirmed that this patch fixes the build error, but not sure
it works or not.  Just build tested.  And note that there there's
nothing interesting in the u-boot-mips tree, sorry.
