usb: musb: core: add common method of getting vbus status
Fix musb_platform_get_vbus_status return value in case of platform implementation is not defined, bringing expected behaviour of musb_platform_get wrapper. Add musb_vbus_show default method to determine VBUS status in case platform method is not defined. Signed-off-by: Roman Alyautdin <ralyautdin@dev.rtsoft.ru> Signed-off-by: Felipe Balbi <balbi@ti.com>
