Switch nVHE tests to QEMU CPU max,sve=off

Now that we can select nVHE using a command line flag, we can ditch
the cortex-a53 workaround for selecting nVHE and use CPU max.
We still need to disable SVE as KVM will refuse to boot in nVHE if the
CPU supports it.

Test: make test, check logs that vhe/nvhe/pkvm modes are correct
