ARM: 7584/1: perf: fix link error when CONFIG_HW_PERF_EVENTS is not selected
Commit e50c5418 (ARM: perf: add guest vs host discrimination) broken the link as perf_instruction_pointer and perf_misc_flags are not defined when CONFIG_HW_PERF_EVENTS is not selected. As it make little sense to try and profile a guest without any HW event, just fallback to the original code when this config option is not selected.
