The SAMA5 and SAM9x5 series both have drive strength options for the PIOs. This patch adds the ability to set one of three hardware options for drive strengths of low, medium or high for the each pin. The actual current output of the chip based on the setting is defined in the datasheets and varies per pins separate from banks and with supply voltage. This patch adds three new dt-bindings that allow setting the strength when configuring pins. By default, no change will be made to the drive strength of a pin from its reset value. Due to the difference between the register addresses of the SAMA5 and SAM9x5 series, a new sama5d3-pinctrl id was added.
