hw/arm/smmuv3: Fix device reset
We currently miss a bunch of register resets in the device reset
function. This sometimes prevents the guest from rebooting after
a system_reset (with virtio-blk-pci). For instance, we may get
the following errors:
invalid STE
smmuv3-iommu-memory-region-0-0 translation failed for iova=0x13a9d2000(SMMU_EVT_C_BAD_STE)
Invalid read at addr 0x13A9D2000, size 2, region '(null)', reason: rejected
invalid STE
smmuv3-iommu-memory-region-0-0 translation failed for iova=0x13a9d2000(SMMU_EVT_C_BAD_STE)
Invalid write at addr 0x13A9D2000, size 2, region '(null)', reason: rejected
invalid STE
