iommu/arm-smmu: Do an ATOS in the fault handler
In order to facilitate debugging of context faults, the result of a
software table walk is currently printed as part of the fault handling.
However, there are certain bugs and error conditions that can't be
caught by doing a software table walk (like missing TLB invalidation or
misbehaving hardware). Add a hardware table walk (via ATOS) to improve
debugging capabilities.
