selftests/powerpc/pmu: Add selftest for checking invalid bits in event code
Some of the bits in the event code is reserved for specific platforms.
Event code bits 52-59 are reserved in power9, whereas in power10, these
are used for programming Monitor Mode Control Register 3 (MMCR3). Bit 9
in event code is reserved in power9, whereas it is used for programming
"radix_scope_qual" bit 18 in Monitor Mode Control Register 1 (MMCR1).
Testcase to ensure that using reserved bits in event code should cause
event_open to fail.
