imx233: fix usb_detect() to be consistent with vbus detection

Browse source 
The STMP3700 has unreliable vbusvalid irq so we need to use
vdd5gtvddio. Therefore, using the vbusvalid bit produces
inconsistent results between events and detect. Fix that
by making power handle all the usb detect stuff.
