This patch moves twl4030-usb to platform_device. Later patches
will come adding proper notifications for twl usb irq events
via sysfs. The files will be placed under
/sys/devices/platform/twl4030-usb/
Also get rid of transceiver mode Kconfig selection, that will be
done by passing the desired mode via platform_data.
