cpufreq: intel_pstate: Use correct scaling factor on Raptor Lake-E

Raptor Lake-E has the same processor ID as Raptor Lake-S, so there is
an entry in intel_hybrid_scaling_factor[] for it.  It does not contain
E-cores though and hybrid_get_cpu_type() returns 0 for its P-cores, so
they get the default "core" scaling factor.  However, the original
Raptor Lake scaling factor for P-cores still needs to be used for
mapping the HWP performance levels of the P-cores in Raptor Lake-E to
frequency, as though they were part of a real hybrid system.

To address this, update hwp_get_cpu_scaling() to return
hybrid_scaling_factor, which is the P-core scaling factor
retrieved from intel_hybrid_scaling_factor[], for all CPUs
that are not enumerated as E-cores.
