Subject: [PATCH 16/16] arch: x86: xen: Mark internal functions static in setup.c

setup.c defines xen_pvmmu_arch_setup and xen_ignore_unusable
used only in this file. So mark them static.

This eliminates the following gcc warnings:
arch/x86/xen/setup.c:561:6: warning: no previous prototype for ‘xen_ignore_unusable’ [-Wmissing-prototypes]
arch/x86/xen/setup.c:831:13: warning: no previous prototype for ‘xen_pvmmu_arch_setup’ [-Wmissing-prototypes]
