From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

Add documentation for pin controller found on RZ/G3S (R9A08G045) SoC.
Compared with RZ/G2{L,UL} RZ/G3S has 82 general-purpose IOs, no slew
rate and output impedance support and more values for drive strength
which needs to be expressed in microamp.
