drivers: soc: qcom: allow setup of pmu events during hotplug

Setup pmu counter functions of rimps memlat driver check cpu_is_hp
flag before creating counters, and the setup of pmu counters will
be called in two places one in probe and other when cpu is coming
up from hotplug path.

The hotplug path will clear cpu_is_hp after the pmu setup calls are
issued, but pmu setup function will not create pmu events as the
cpu_is_hp flag not cleared at this point, this results in pmu
counters not getting setup even cpu is up from the hotplug path.

Add a parameter to these functions indicating from which path these
are called and update the logic accordingly to allow creation of
pmu events when core is coming up.
