Subject: [PATCH 01/11] iommu/vt-d: Remove the CONFIG_X86 wrapping from iommu init hook

From: "Vineeth Pillai (Google)" <vineeth@...byteword.org>

iommu init hook is wrapped in CONFI_X86 and is a remnant of dmar.c when
it was a common code in "drivers/pci/dmar.c". This was added in commit
(9d5ce73a64be2 x86: intel-iommu: Convert detect_intel_iommu to use
iommu_init hook)

Now this is built only for x86. This config wrap could be removed.
