Subject: [PATCH 04/15] cpufreq: acpi: Set policy->boost_supported

With a later commit, the cpufreq core will call the ->set_boost()
callback only if the policy supports boost frequency. The
boost_supported flag is set by the cpufreq core if policy->freq_table is
set and one or more boost frequencies are present.

For other drivers, the flag must be set explicitly.
