Documentation: intel_pstate: Fix description of asymmetric packing with SMT
Patchset [1], including commits
046a5a95c3b0 ("x86/sched/itmt: Give all SMT siblings of a core the same priority")
995998ebdebd ("x86/sched: Remove SD_ASYM_PACKING from the SMT domain flags")
overhauled asym_packing handling in the scheduler on x86 hybrid
processors with SMT. It removed SD_ASYM_PACKING from the x86 SMT
scheduling domain and made all SMT siblings of a core share the same
priority. As a result, asym_packing operates only across physical
cores, spreading tasks among them and only using idle SMT siblings
once all physical cores are busy.
Fix the documentation to reflect this behavior.
