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

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.
