Due to commit 2b7deea3ec ("Revert "kvm: selftests: move base
kvm_util.h declarations to kvm_util_base.h"") kvm selftests now
requires explicitly including ucall_common.h when needed. The commit
added the directives everywhere they were needed at the time, but, by
merge time, new places had been merged for RISC-V. Add those now to
fix RISC-V's compilation.
Fixes: dee7ea42a1 ("Merge tag 'kvm-x86-selftests_utils-6.10' of https://github.com/kvm-x86/linux into HEAD")

SBI PMU test comprises of multiple tests and user may want to run
only a subset depending on the platform. The most common case would
be to run all to validate all the tests. However, some platform may
not support all events or all ISA extensions.
The commandline option allows user to disable any set of tests if
they want to.

Add a test for verifying overflow interrupt. Currently, it relies on
overflow support on cycle/instret events. This test works for cycle/
instret events which support sampling via hpmcounters on the platform.
There are no ISA extensions to detect if a platform supports that. Thus,
this test will fail on platform with virtualization but doesn't
support overflow on these two events.

Verify PMU snapshot functionality by setting up the shared memory
correctly and reading the counter values from the shared memory
instead of the CSR.

This test implements basic sanity test and cycle/instret event
counting tests.
