[AMD Public Use] v1: Use the current and custom pstate frequencies to track the current and user-set min/max values in manual and determinism mode. Previously, only actual_* value was used to track the currrent and user requested value. The value will get reassigned whenever user requests a new value with pp_od_clk_voltage node. Hence it will show incorrect values when user requests an invalid value or tries a partial request without committing the values. Separating out to custom and current variable fixes such issues. v2: Remove redundant if-else check Signed-off-by: Lijo Lazar
