b8daa7ceac KVM: arm64: selftests: Add unsanitised helpers for VGICv3 creation
vgic_v3_setup() has a good bit of sanity checking internally to ensure
that vCPUs have actually been created and match the dimensioning of the
vgic itself. Spin off an unsanitised setup and initialization helper so
vgic initialization can be wired in around a 'default' VM's vCPU
creation.

b712afa7a1 KVM: arm64: selftests: Add helper to check for VGICv3 support
Introduce a proper predicate for probing VGICv3 by performing a 'test'
creation of the device on a dummy VM.

a5022da5f9 KVM: arm64: selftests: Initialize VGICv3 only once
vgic_v3_setup() unnecessarily initializes the vgic twice. Keep the
initialization after configuring MMIO frames and get rid of the other.

67730e6c53 KVM: selftests: Use canonical $(ARCH) paths for KVM selftests directories
Use the kernel's canonical $(ARCH) paths instead of the raw target triple
for KVM selftests directories.  KVM selftests are quite nearly the only
place in the entire kernel that using the target triple for directories,
tools/testing/selftests/drivers/s390x being the lone holdout.

Using the kernel's preferred nomenclature eliminates the minor, but
annoying, friction of having to translate to KVM's selftests directories,
e.g. for pattern matching, opening files, running selftests, etc.

Opportunsitically delete file comments that reference the full path of the
file, as they are obviously prone to becoming stale, and serve no known
purpose.
