[U-Boot] [PATCH v4 3/3] musb_udc : Fix compile warning.

[Harman Sohanpal]

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.
