iommu/iommu-debug: Add secure_attach debugfs file
It can be useful to perform tests on secure domains. Add support for
this with a "secure_attach" file that will also set the
DOMAIN_ATTR_SECURE_VMID to the value written to the file.
Example usage:
# cd /sys/kernel/debug/iommu/tests/<device>
# echo 0xA > secure_attach
# echo 0x1000,0x1000,0x1000,1 > map
# echo 0x1000,0x1000 > unmap
# echo 0 > secure_attach
