cpufreq: amd-pstate: Cap the CPPC.max_perf to nominal_perf if CPB is off

Browse source

When Core Performance Boost is disabled by the user, the
CPPC_REQ.max_perf should not exceed the nominal_perf since by definition
the frequencies between nominal_perf and the highest_perf are in the
boost range. Fix this in amd_pstate_update()
