usb: musb: sunxi: make unexported symbols static

Browse Source 
The sunxi_musb_dma_controller_create and _destroy are not exported
or used outside the driver, so fix sparse warnings by making these
two static:

drivers/usb/musb/sunxi.c:357:23: warning: symbol 'sunxi_musb_dma_controller_create' was not declared. Should it be static?
drivers/usb/musb/sunxi.c:363:6: warning: symbol 'sunxi_musb_dma_controller_destroy' was not declared. Should it be static?
