Since commit 28128c61e08e ("kconfig.h: Include compiler types to avoid
missed struct attributes"), <linux/kconfig.h> pulls in kernel-space
headers to unrelated file.
Commit 0f9da844d877 ("MIPS: boot: Define __ASSEMBLY__ for its.S build")
suppressed the build error by defining __ASSEMBLY__, but ITS (i.e. DTS)
is not assembly, and should not include <linux/compiler_types.h> in the
first place.
Looking at arch/s390/tools/Makefile, host programs gen_facilities and
gen_opcode_table now pull in <linux/compiler_types.h> as well.
The motivation for that commit was to define necessary attributes
before any struct is defined. Obviously, this happens only in C.
It is enough to include <linux/compiler_types.h> only when compiling
C files, and only when compiling kernel space.
Move the <linux/compiler_types.h> inclusion to c_flags.

I will also send a correct fix-up for MIPS Makefile later.
