Subject: [PATCH] ARM: dts: imx6sx-sdb: Add power supply property to Root Port
 node

Add the power supply property to the Root Port child node to support the
new PCI pwrctrl framework.

Legacy power supply property is retained for backward compatibility with
existing kernels. New device trees should specify power supply at the
Root Port level to utilize the pwrctrl framework.
