usb: musb: pass configuration specifics via pdata
Use platform_data to pass musb configuration-specific details to musb driver. This patch will prevent that other platforms selecting HAVE_CLK and enabling musb won't break tree building. The other parts of it will come when linux-omap merge up more omap2/3 board-files.
