[PATCH v2 4/5] perf/x86: Move events_sysfs_show outside CPU_SUP_INTEL

[Huang Rui <ray.huang@amd.com>]

This patch moves events_sysfs_show outside CONFIG_CPU_SUP_INTEL,
because this interface will be also used on AMD power reporting
performance event.

Otherwise, below build error would be encountered:
