There is no harm in declaring the function prototypes even if nothing implements them, and when CONFIG_DM_USB=y the various usb functions are available regardless of any controller drivers being enabled.
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.

Changes in v2: -Simply always define the function prototypes instead of adding yet another condition to the already unwieldly #if def ... || def ... condition
