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.
