When CONFIG_DM_USB=y the various usb functions are available regardless of any controller drivers being enabled, so always the usb function prototypes when CONFIG_DM_USB=y.
This fixes compile warnings due to missing prototypes on ARCHs where the ARCH Kconfig always enables CONFIG_DM_USB and various usb drivers.
One could argue that in the case of no controllers CONFIG_DM_USB should not be set, but this problem is typically seen during bringup of boards which do actually have usb controllers.

What would happen in case we instead dropped this horrible ifdef altogether, do you think it'd break anything ?
I've not audited the code, but I believe that it only declares a bunch of function prototypes, so I think that dropping the entire #ifdef is fine.
So do I :)
