cpufreq: intel_pstate: Set non-turbo capacity to HWP_GUARANTEED_PERF()

Setting cpu->capacity_perf to cpu->pstate.max_pstate_physical in the
"no turbo" case is inconsistent with what happens elsewhere in the
driver and causes arch_scale_cpu_capacity() to be incorrect.  It also
skews arch_scale_freq_capacity() which ends up differing from 1024 for
the guaranteed P-state.

Address that by setting capacity_perf to HWP_GUARANTEED_PERF() in the
"no turbo" case.
