On First controller of CQS/CQM platforms, usb-role-swtich is controller 
by PM4125 and on second controller of CQS/CQM platforms, and both 
controllers of IQS, its controller by Cypress PD controller. I will push 
out the PM4125 changes in a different patch set since couple of issues 
are under debug. And the cypress pd controller changes are still under 
development. Hence enabled both controllers in device mode for now.
