To avoid leaking the struct musb allocated by musb_init_controller()

But musb_init_controller() does more, such as calling sunxi_musb_init()

Not calling sunxi_musb_init() causes the musb controller to stop working

clocks.

This commit fixes this by removing the caching of the struct returned
from musb_init_controller(), it replaces this by free-ing the allocated
memory in musb_usb_remove() and calling musb_usb_remove() on
