dt-bindings: pinctrl: renesas,r9a09g077: Document pin configuration properties

Browse source

Document the pin configuration properties supported by the RZ/T2H
pinctrl driver.

The RZ/T2H SoC allows configuring several electrical characteristics
through the DRCTLm (I/O Buffer Function Switching) registers. These
registers control drive strength, bias configuration, Schmitt trigger
input, and output slew rate.
