[PATCH] ARM: mach-virt: fix PMUv3 dependendency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

Selecting a ARM_PMUV3 from a platform option breaks the build
when CONFIG_ARM_PMU is not already set:

WARNING: unmet direct dependencies detected for ARM_PMUV3
  Depends on [n]: PERF_EVENTS [=y] && HW_PERF_EVENTS [=n] && (ARM [=y] && CPU_V7 [=y] || ARM64)
  Selected by [y]:
  - ARCH_VIRT [=y] && ARCH_MULTI_V7 [=y] && PERF_EVENTS [=y]
