Subject: [PATCH] docs/x86: Update AMD IOMMU specification location

The current link to the AMD I/O Virtualization Technology IOMMU
specification (document 48882) in Documentation/arch/x86/iommu.rst
is outdated and points to a defunct URL on the AMD website.

Update the link in Documentation/arch/x86/iommu.rst to the current stable
location for the specification. This ensures users can easily access the
required architectural details.
