ARM: dts: msm: Add secondary USB host for MSM8994 



The MSM8994 contains a secondary instance of a USB host
controller paired with the new QUSB2 PHY. Add device tree
nodes to describe them.

Leave these disabled in the base msm8994.dtsi and enable
them only on CDP, as VBUS power is required. Also add
the VBUS regulator device which is controled by GPIO 5
on the PMI8994.
