Ok, Will change this and send v2.

Doing that also fails because path for 'arch/mips/include' is not
added also because we are compiling in x86_64.
Looking into other drivers I see the way to avoid this kind of
platform specific stuff is adding related paths in
cflags. So I don't really know if there is another way.
