The perf-to-frequency scaling factors are used by intel_pstate on hybrid
platforms to cast performance levels to frequency on different types of
CPUs which is needed because the generic cpufreq sysfs interface works
in the frequency domain.

For some hybrid platforms already in the field, the scaling factors are
known, but for others (including some upcoming ones) they most likely
will be different and the only way to get them that scales is to use
information provided by the platform firmware.  In this particular case,
the requisite information can be obtained via CPPC.

If the P-core hybrid scaling factor for the given processor model is not
known, use CPPC to compute hybrid scaling factors for all CPUs.

Since the current default hybrid scaling factor is only suitable for a
few early hybrid platforms, add intel_hybrid_scaling_factor[] entries
for them and initialize the scaling factor to zero ("unknown") by
default.

I encountered an issue where Perfetto sometimes fails to display the
blocked function when a thread enters the D state.

The problem arises from the caller value in the trace_sched_blocked_reason,
and I observed the following outputs while using bpftrace:

bpftrace -e 't:sched:sched_blocked_reason /args.caller > 0 &&
args.caller < 0xFFFFFFFF/ {@[args.caller]=count();}'

@[0x1]: 23

When try_to_wake_up is waking a thread executing __schedule, it can trigger
the trace_sched_blocked_reason. This function attempts to obtain the
thread's backtrace using __get_wchan. However, __get_wchan requires the
thread to be blocking in cpu_switch_to, which is not always the case.

To resolve this, we can move the trace_sched_blocked_reason call inside
__schedule to ensure accurate caller information.
