This patch fix the compile warning : implicit declaration of musb_platform_init when CONFIG_MUSB_UDC is defined. The extern musb_platform_init was declared in musb_hcd.h but no such extern function was declared for musb_udc. So a common function has been declared in musb_core.h which can be used for both host mode and device mode.
