ARM: dts: msm: Add usb-conn-gpio & pinctrl nodes for Cinder

Cinder has no PMI, so we are using usb-conn-gpio driver to detect the
USB role based on the states of Vbus & Vid GPIO pins. Also added nodes
for Vbus, Vid, Vbus-out pins. Added usb-role-switch property usb0,
so that dwc3-msm driver can register for role switch. Port nodes
were added to latch usb-conn-gpio and dwc3-msm drivers together.
