usb: musb: sunxi: Fix NULL ptr deref when gadget is registered before musb
Stop using the return value of platform_device_register_full() to get to
the struct musb in sunxi_musb_work(). If a gadget has been registered
(insmod-ed) before the musb driver, then musb_start will get called
from the musb_core probe function and sunxi_musb_work() may run before
platform_device_register_full() has returned.
Instead store a pointer to struct musb in struct sunxi_glue when
sunxi_musb_enable gets called. Note that sunxi_musb_enable always gets
called before sunxi_musb_work() can run.
