KVM: riscv: selftests: Allow number of interrupts to be configurable
It is helpful to vary the number of the LCOFI interrupts generated
by the overflow test. Allow additional argument for overflow test
to accommodate that. It can be easily cross-validated with
/proc/interrupts output in the host.

KVM: riscv: selftests: Change command line option
The PMU test commandline option takes an argument to disable a
certain test. The initial assumption behind this was a common use case
is just to run all the test most of the time. However, running a single
test seems more useful instead. Especially, the overflow test has been
helpful to validate PMU virtualizaiton interrupt changes.
Switching the command line option to run a single test instead
of disabling a single test also allows to provide additional
test specific arguments to the test. The default without any options
remains unchanged which continues to run all the tests.

KVM: riscv: selftests: Add commandline option for SBI PMU test
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.

KVM: riscv: selftests: Add a test for counter overflow
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.
