This patch is to make the error log more clear for fine grain tuning
function, it covers Raven/Raven2/Picasso/Renoir/Vangogh.
The fine grain tuning function uses the sysfs file -- pp_od_clk_voltage,
but only when another sysfs file -- power_dpm_force_performance_level is
switched to "manual" mode, it is allowed to access "pp_od_clk_voltage".
