Add new dt bindings for charge chip control. The charge chip control dt configuration is used by the driver 'cros-ec-charge-state', which is added in the commit "platform/chrome: cros_ec_charge_state: add new driver to control charge". As these charge chip controls are connected under the ChromeOS Embedded Controller (EC), also add the patternProperties to the mfd/google,cros-ec bindings.
