[U-Boot] [PATCH] dm: usb.h: Always declare usb func. prototypes when CONFIG_DM_USB=y

[Hans de Goede]

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.
