When running in slave mode (no clock master), there is no way to determine the real wirespeed on the MADI link (single/double/quad speed). Like physical gear, simply provide the user with a tristate switch to select the appropriate format.

Apparently, there are multiple old firmware revisions in the wild for the PCI RME MADI cards. Just add them to the list of supported devices and treat them like their modern counterparts.
