Add support for AMD MPERF/APERF
Starting with Family 0x10, model 10 processors, some AMD processors
will have support for the APERF/MPERF MSRs. This patch adds the
checks necessary to support those MSRs.
It also makes the get_measured_perf function defined inside cpufreq.c
driver independent. max_freq is taken from the policy definition
instead of being a private argument in struct acpi_cpufreq_data.
The struct member is entirely removed from the function since it
is no longer used.
