    This reverts commit 3b16f626.
    
    Selecting a Kconfig option that has its own set of dependencies tends to
    end badly, and in this case 'randconfig' builds blew up on 32-bit ARM
    where ARM_PMUV3 was being selecting with HW_PERF_EVENTS=n:
    
      |    drivers/perf/arm_pmuv3.c:68:5: error: use of undeclared identifier 'DTLB'
      |            [C(DTLB)][C(OP_READ)][C(RESULT_ACCESS)] = ARMV8_PMUV3_PERFCTR_L1D_TLB,
      |               ^
      |    fatal error: too many errors emitted, stopping now [-ferror-limit=]
      |    20 errors generated.
      |
      | Kconfig warnings: (for reference only)
      |    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]
    
    As suggested by Marc, just drop the 'select' clause altogether by
    reverting the patch which introduced it.
