Subject: [PATCH 49/58] x86: init: Mark internal functions iommu_init_noop and iommu_shutdown_noop static

Nothing outside of arch/x86/kernel/x86_init.c references iommu_init_noop
or iommu_shutdown_noop, so mark them static.  This eliminates warnings
from GCC (-Wmissing-prototypes) and Sparse (-Wdecl).

arch/x86/kernel/x86_init.c:29:115: warning: no previous prototype for ‘iommu_init_noop’ [-Wmissing-prototypes]
arch/x86/kernel/x86_init.c:30:6: warning: no previous prototype for ‘iommu_shutdown_noop’ [-Wmissing-prototypes]
