The fifo_mode parameter is used to select endpoint allocation mode.
fifo_mode = 0 is used to let the driver autoconfigure the endpoints.
In this case 2 banks are allocated for isochronous endpoints and
only one bank is allocated for the rest of the endpoints.
In this case, for ep1 2 banks are allocated if it works in isochronous
mode and only 1 bank otherwise. For the rest of the endpoints
only 1 bank is allocated.
fifo_mode = 1 is a generic maximum fifo size (1024 bytes) configuration
allowing the usage of ep1 - ep6
