x86: set_highmem_pages_init() cleanup

Impact: cleanup

This patch moves set_highmem_pages_init() to arch/x86/mm/highmem_32.c.

The declaration of the function is kept in asm/numa_32.h because
asm/highmem.h is included only if CONFIG_HIGHMEM is enabled so we
can't put the empty static inline function there.
