In U-Boot, SoC-specific headers are placed in arch/$(ARCH)/include/asm/arch-$(SOC) and a symbolic link to that directory is created at the early stage of the build process.
Creating and removing a symbolic link during the build is not preferred. In fact, Linux Kernel did away with include/asm-$(ARCH) directories a long time time ago.
As for ARM, now it is possible to collect SoC sources into arch/arm/mach-$(SOC). It is also reasonable to move SoC headers into arch/arm/mach-$(SOC)/include/mach.
This commit prepares for that. If the directory arch/$(ARCH)/mach-$(SOC)/include/mach exists, a symbolic to that directory is created. Otherwise, a symbolic link to arch/$(ARCH)/include/asm/arch-$(SOC) or arch-$(CPU) is created.

Applied to u-boot/master, thanks!
