usb: musb: Make busctl_offset an io-op rather then a define
The Allwinner (sunxi) implementation of the musb has its busctl registers indexed by the MUSB_INDEX register rather then in a flat address space. This commit turns MUSB_BUSCTL_OFFSET from a macro into an io-op which can be overridden from the platform ops.
