Doing this in amd_iommu_prepare() is too late for it, in particular, to

(luckily) pretty simple, (pretty importantly) without breaking
amd_iommu_prepare()'s logic to prevent multiple processing.
This involves moving table checksumming, as
amd_iommu_get_supported_ivhd_type() -> get_supported_ivhd_type() will
now be invoked before amd_iommu_detect_acpi() -> detect_iommu_acpi(). In
the course of doing so stop open-coding acpi_tb_checksum(), seeing that
we have other uses of this originally ACPI-private function elsewhere in
the tree.
