JIRA DNVGPU-123 function was added to retrieve V for F or F for V for a given clock domain. Clock domain can be master or slave. F or V can be intermediate point between two successive V or F values in VF table. VF table should be cached before calling this function. A F value below Fmin will return Vmin. F > Fmax will return error A V value above Vmax wil return F max. A V value below Vmin will return error.
