Use u32 instead of uint32_t to make the KVM selftests code more concise
and more similar to the kernel (since selftests are primarily developed
by kernel developers).
This commit was generated with the following command:
git ls-files tools/testing/selftests/kvm | xargs sed -i 's/uint32_t/u32/g'
Then by manually adjusting whitespace to make checkpatch.pl happy.
No functional change intended.

Use u64 instead of uint64_t to make the KVM selftests code more concise
and more similar to the kernel (since selftests are primarily developed
by kernel developers).
This commit was generated with the following command:
git ls-files tools/testing/selftests/kvm | xargs sed -i 's/uint64_t/u64/g'
Then by manually adjusting whitespace to make checkpatch.pl happy.
Include <linux/types.h> in include/kvm_util_types.h, iinclude/test_util.h,
and include/x86/pmu.h to pick up the tools-defined u64. Arguably, all
headers (especially kvm_util_types.h) should have already been including
stdint.h to get uint64_t from the libc headers, but the missing dependency
only rears its head once KVM uses u64 instead of uint64_t.
No functional change intended.

[sean: rename pread_uint64() => pread_u64, expand on types.h include]

HVCs are taken within the VM when EL2 is in use. Ensure tests use the
SMC instruction when running at EL2 to interact with the host.

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.
