[PATCH v5 7/7] ARM: dts: ti: cpcap-mapphone: add USB safe pinctrl state

[Ivaylo Dimitrov]

Add a pinctrl state that configures the USB interface pins into a safe
GPIO configuration. This allows the CPCAP USB PHY driver to place the
pins into a defined state whenever the USB interface is not active.
