Subject: [PATCH 012/228] cpufreq: sparc: call cpufreq_frequency_table_get_attr()

This exposes frequency table of driver to cpufreq core and is required for core
to guess what the index for a target frequency is, when it calls
cpufreq_frequency_table_target(). And so this driver needs to expose it.
