Support PVT HW configuration

Set the device tree default to PVT pin assignment. To support older
boards:
* Set wifi test enable pin for both pin assignments.
* Create two regulators for VBUS and use overlay on usb to control the
configuration. We can't overlay on usb0_vbus because overlay doesn't
support deleting properties (enable-active-high)

An OTG overlay is created to support OTG VBUS for the boards from older
builds. The user need to enable it per flash in /boot/overlays.txt
