Subject: [PATCH] iommu/amd: define 'amd_ivhd_dev_flags_list' in header

The 'amd_ivhd_dev_flags_list' is used in the amd_iommu_types.h
header but not defined, so add the definition to remove the
following sparse warning:

drivers/iommu/amd/init.c:182:1: warning: symbol 'amd_ivhd_dev_flags_list' was not declared. Should it be static?
