[U-Boot] [RFC PATCH 21/21] ARM: prepare for including <mach/*.h>

[Masahiro Yamada]

This commit adds $(srctree)/arch/arm/$(machdirs)/include/mach to
the headers search path.

It allows us to replace "#include <asm/arch/foo.h>" with
"#include <mach/foo.h>".  As "#include <asm/arch/foo.h>" is still
supported, we can modify each file one by one.
