usb: musb: sunxi: Add support for musb controller in A31 SoC
The A31 SoC uses the same musb controller as found in earlier SoCs, but it is hooked up slightly different. Its SRAM is private and no longer controlled through the SRAM controller, and its reset is controlled via a separate reset controller. This commit adds support for this setup.
