: Fixes to EL2 register visibility, courtesy of Marc Zyngier
:
: - Expose EL2 VGICv3 registers via the VGIC attributes accessor, not the
: KVM_{GET,SET}_ONE_REG ioctls
:
: - Condition visibility of FGT registers on the presence of FEAT_FGT in
: the VM

Add the EL2 registers and the eventual dependencies, effectively
doubling the number of test vectors. Oh well.

Describing the dependencies between registers and features is on
the masochistic side of things, with hard-coded values that would
be better taken from the existing description.
Add a couple of helpers to that effect, and repaint the dependency
array. More could be done to improve this test, but my interest is
wearing thin...

One difference here with other pseudo-firmware bitmap registers
is that the default/reset value for the supported hypercall
function-ids is 0 at present. Hence, modify the test accordingly.

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.
