[RFC PATCH 08/15] perf/apple_m1: Remove driver-specific throttle support

[kan.liang@linux.intel.com]

From: Kan Liang <kan.liang@linux.intel.com>

The throttle support has been added in the generic code. Remove
the driver-specific throttle support.

Besides the throttle, perf_event_overflow may return true because of
event_limit. It already does an inatomic event disable. The pmu->stop
is not required either.
