usb: musb: core: fix order of arguments to ulpi write callback
There is a bit of a mess in the order of arguments to the ulpi write callback. There is int ulpi_write(struct ulpi *ulpi, u8 addr, u8 val) in drivers/usb/common/ulpi.c; struct usb_phy_io_ops { ... int (*write)(struct usb_phy *x, u32 val, u32 reg); } in include/linux/usb/phy.h. The callback registered by the musb driver has to comply to the latter, but up to now had "offset" first which effectively made the function broken for correct users. So flip the order and while at it also switch to the parameter names of struct usb_phy_io_ops's write.
