This patch adds the option to poll vbus status to the s3c24xx udc driver.
Machines that do not route the USB vbus signal to a GPIO can use this
mechanism as an alternate way for the udc driver to detect the usb
connect/disconnect state, which is useful (for example) to enable the
link up/down state to be determined for the g_ether gadget.
