Enable primary USB controller on QCS615 Ride platform. The primary USB
controller is made "peripheral", as this is intended to be connected to
a host for debugging use cases.

For using the controller in host mode, changing the dr_mode and adding
appropriate pinctrl nodes to provide vbus would be sufficient.

 From schematic, we need use the "vreg_l12a" for vdda-pll-supply.

 From bindings, we also can see need 1.8V(VREG_L12A_1P8) not 
2.9V(VREG_L2A_2P96):

62vdda-pll-supply:
63     description:
64       Phandle to 1.8V regulator supply to PHY refclk pll block.

Thanks for pointing it out. It is supposed to be L12. Will fix up in v2.
