[PATCH 7/9] dt-bindings: pinctrl: renesas,rzg2l-pinctrl: Document the I3C standby property

[Claudiu Beznea]

From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>

The I3C pins on the Renesas RZ/G3S SoC can be configured in standby mode
when operating in I2C mode. According to the RZ/G3S HW manual (Rev. 1.20),
when standby mode is selected, the output is fixed at Hi-Z and no data is
transferred internally, even if data is received from outside.

Document the renesas,i3c-standby property.
