ARM: dts: imx53-qsb: Make USBH1 functional
mx53qsb uses GPIO7_8 to turn on VBUS, so add support for it. Also specify the PHY type in the device tree. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Tested-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
