    Subject: cfg/intel.scc: Include iommu.scc for Arrowlake boot support
    Date: Mon, 14 Apr 2025 11:55:45 +0530

    Move features/iommu/iommu.scc from bsp/intel-common/intel-corei7-64.scc and
    bsp/intel-x86/intel-x86.scc to cfg/intel.scc to eliminate redundancy and ensure
    IOMMU support (CONFIG_INTEL_IOMMU=y, etc.) is enabled for genericx86-64
    on Intel Arrowlake, resolving boot issues.

    This changes is needed in 6.12 as well as master branch.
