Through the dpio_get_attributes() firmware call the dpio driver has access to the QBMAN clock frequency. Extend the structure which holds the firmware's response so that we can have access to this information. This will be needed in the next patches which also add support for interrupt coalescing which needs to be configured based on the frequency.
