arm64: Fix build failure when HARDLOCKUP_DETECTOR_PERF is enabled
If HARDLOCKUP_DETECTOR_PERF is selected but HW_PERF_EVENTS is not, then
the associated watchdog driver will fail to link:
| aarch64-linux-ld: Unexpected GOT/PLT entries detected!
| aarch64-linux-ld: Unexpected run-time procedure linkages detected!
| aarch64-linux-ld: kernel/watchdog_hld.o: in function `hardlockup_detector_event_create':
| >> watchdog_hld.c:(.text+0x68): undefined reference to `hw_nmi_get_sample_period
Change the Kconfig dependencies so that HAVE_PERF_EVENTS_NMI requires
the hardware PMU driver to be enabled, ensuring that the required
symbols are present.
