LoongArch: Lately init pmu after smp is online

There is an smp function call named reset_counters() to init PMU
registers of every CPU in PMU initialization state. It requires that all
CPUs are online. However there is an early_initcall() wrapper for the
PMU init funciton init_hw_perf_events(), so that pmu init funciton is
called in do_pre_smp_initcalls() which before function smp_init().
Function reset_counters() cannot work on other CPUs since they haven't
boot up still.

Here replace the wrapper early_initcall() with pure_initcall(), so that
the PMU init function is called after every cpu is online.
