Subject: [PATCH v2 1/1] iommu/vt-d: Move intel_iommu_ops to header file

Compiler is not happy about hidden declaration of intel_iommu_ops.

.../iommu.c:414:24: warning: symbol 'intel_iommu_ops' was not declared. Should it be static?

Move declaration to header file to make compiler happy.

Signed-off-by: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

v2: made sure it compiles with IRQ_REMAP=y, INTEL_IOMMU=n (Lu)
