Use the no_log version of readl_relaxed when reading out the
counter values for CPUs to reduce the amount of logging in
RTB Logs. Scheduler activity is very frequent and clogs up the
buffer, which can potentially reduce the amount of useful logs.

Add a ready callback, which will be called when a CPU policy is ready.
As a part of this callback, register the corresponding CPU cooling
device.

Register child devices once a successful probe is done. This
will enable the dependent child devices to be probed immediately after
the cpufreq probe is done.

The scheduler needs a way to track cpu cycle counts,
return the total cycle count by adding the difference between
the current cycle count and the previous from reading the EPSS
cycle counters.

Given that there are no issues selecting a desired_state before
EPSS is enabled for a particular cluster, let's skip the check
for enable bit on clusters to give better flexibility to the
cpufreq driver to probe successfully on configuration where
not all clusters are enabled.

The topology driver keeps track of the current capacity of a CPU and
make it available via arch_scale_freq_capacity(). The PELT load
tracking in the scheduler and energy-aware task placement are the
clients of this API. Hence notify the new frequency to the topology
driver during frequency transition.

Improve the calling convention detection to use qcom_scm_call_atomic
and not blindly assume 32-bit mode if the checks fails.
__qcom_scm_is_call_available() cannot be used directly here as we want
an atomic variant of is_call_available(). This is also a necessary
requirement later when merging in legacy convention.
