powerpc/pseries/Kconfig: Enable CONFIG_VPA_PMU to be used with KVM

Browse Source 
Currently, CONFIG_VPA_PMU is not enabled by default, and consequently
cannot be used for KVM guests at all, unless explicitly enabled on
host kernel.

Mark CONFIG_VPA_PMU as "default m" to ensure it is available when KVM is
being used.

Enable access to the VPA PMU counters via perf. This enables
code that support measurement for KVM on PowerVM(KoP) feature.
