Assert that the vCPU exits to userspace with KVM_SYSTEM_EVENT_SUSPEND if
the guest calls PSCI SYSTEM_SUSPEND. Additionally, guarantee that the
SMC32 and SMC64 flavors of this call are discoverable with the
PSCI_FEATURES call.

Split up the current test into several helpers that will be useful to
subsequent test cases added to the PSCI test suite.

selftests: KVM: Use KVM_SET_MP_STATE to power off vCPU in psci_test2022-05-04T08:28:46ZOliver Uptonoupton@google.com2022-05-04T03:24:44Zurn:sha1:d135399a97cc3e27716a8e468a5fd1a209346831
Setting a vCPU's MP state to KVM_MP_STATE_STOPPED has the effect of
powering off the vCPU. Rather than using the vCPU init feature flag, use
the KVM_SET_MP_STATE ioctl to power off the target vCPU.

selftests: KVM: Create helper for making SMCCC calls2022-05-04T08:28:45ZOliver Uptonoupton@google.com2022-05-04T03:24:43Zurn:sha1:694e3dcc47471b8b409a0ef647319b746eabcb3a
The PSCI and PV stolen time tests both need to make SMCCC calls within
the guest. Create a helper for making SMCCC calls and rework the
existing tests to use the library function.

There are other interactions with PSCI worth testing; rename the PSCI
test to make it more generic.
No functional change intended.
