usb: gadget: udc: renesas_usb3: fix double phy_put()

BugLink: http://bugs.launchpad.net/bugs/1790188
commit 8223b2f89ca63e203dcb54148e30d94979f17b0b upstream.

This patch fixes an issue that this driver cause double phy_put()
calling. This driver must not call phy_put() in the remove because
the driver calls devm_phy_get() in the probe.
