[PATCH] arch/x86/mm/init_32.c: quiet sparse noise; local functions should be static

[H Hartley Sweeten <hartleys@visionengravers.com>]

Local functions should be marked static.  This quiets the following
sparse noise:

warning: symbol 'lowmem_pfn_init' was not declared. Should it be static?
warning: symbol 'highmem_pfn_init' was not declared. Should it be static?
