    generic_ehci_fdt: fix driver softc size
    
    This subclass declares its own softc structure adding necessary members
    after the embedded ehci_softc_t. The full size of the struct must be
    included in the driver declaration, otherwise the allocation backing the
    softc is not guaranteed to be large enough.
