pinctrl: renesas: Factor out common R-Car Gen3 bias handling
All pin control drivers for R-Car Gen3 SoCs contain identical bias handling. Reduce code duplication by moving it to the common pinctrl.c code. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/20201028151637.1734130-6-geert+renesas@glider.be
