[PATCH -tip] x86: pci-swiotlb.c swiotlb_dma_ops should be static

[Jaswinder Singh Rajput]

Impact: reduce kernel size a bit, address sparse warning

Addresses the problem pointed out by this sparse warning:
  arch/x86/kernel/pci-swiotlb.c:53:20: warning: symbol 'swiotlb_dma_ops' was not declared. Should it be static?

For x86: swiotlb_dma_ops can be static, because it's not used outside pci-swiotlb.c
