Subject: [PATCH 3.16.y-ckt 121/165] ARM: imx6qdl-sabresd: set swbst_reg as vbus's parent reg

3.16.7-ckt9 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Chen <peter.chen@...escale.com>

commit 40f737791d4dab26bf23a6331609c604142228bd upstream.

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.
