usb: dwc3: shutdown usb_phy when removing the device
We call usb_phy_init() from dwc3_core_init() during probe, so adding usb_phy_shutdown() to dwc3_core_exit() while removing the device so we don't keep PHYs turned on, consuming power, unnecessarily. Signed-off-by: Vivek Gautam <gautam.vivek@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
