pinctrl: rockchip: fix pinmux bits for RK3328 GPIO3-B pins
[ Upstream commit 5ef6914e0bf578357b4c906ffe6b26e7eedb8ccf ] The pinmux bits for GPIO3-B1 to GPIO3-B6 pins are not explicitly specified in RK3328 TRM, however we can get hint from pad name and its correspinding IOMUX setting for pins in interface descriptions. The correspinding IOMIX settings for these pins can be found in the same row next to occurrences of following pad names in RK3328 TRM. GPIO3-B1: IO_TSPd5m0_CIFdata5m0_GPIO3B1vccio6 GPIO3-B2: IO_TSPd6m0_CIFdata6m0_GPIO3B2vccio6 GPIO3-B3: IO_TSPd7m0_CIFdata7m0_GPIO3B3vccio6 GPIO3-B4: IO_CARDclkm0_GPIO3B4vccio6 GPIO3-B5: IO_CARDrstm0_GPIO3B5vccio6 GPIO3-B6: IO_CARDdetm0_GPIO3B6vccio6 Add pinmux data to rk3328_mux_recalced_data as mux register offset for these pins does not follow rockchip convention.
