pinctrl: rockchip: only map bank0-pull-region when pmu regmap missing
When the pmu registers are supplied through a syscon regmap we do not need to map the registers ourself. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Tested-by: Max Schwarz <max.schwarz@online.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
