agp/intel: Use per device iommu check
The IOMMU subsystem has already provided an interface to query whether
the IOMMU hardware is enabled for a specific device. This changes the
check from Intel specific intel_iommu_gfx_mapped (globally exported by
the Intel IOMMU driver) to probing the presence of IOMMU on a specific
device using the generic device_iommu_mapped().
This follows commit cca084692394a ("drm/i915: Use per device iommu check")
which converted drm/i915 driver to use device_iommu_mapped().
