[PATCH] ARM: simplify the build rule of mach-types.h

From: Masahiro Yamada
Date: Thu May 27 2021 - 23:51:32 EST


The directory of mach-types.h is created a couple of lines above:

_dummy := $(shell [ -d '$(kapi)' ] || mkdir -p '$(kapi)') \

The 'mkdir -p' command is redundant.

scripts/Kbuild.include defines real-prereqs as a shorthand for
$(filter-out $(PHONY),$^). Let's use it to simplify the code.
