ARM: imx6sl-evk: set swbst_reg as vbus's parent reg

USB vbus 5V is from PMIC SWBST, so set swbst_reg as vbus's parent reg, it fixed a bug that the voltage of vbus is incorrect due to swbst_reg is disabled after boots up. Cc: stable@vger.kernel.org Signed-off-by: Peter Chen <peter.chen@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
