The pinmux bits for GPIO2-B7 is recalculated so it remain unchanged. The pinmux bits for GPIO3-B1 to GPIO3-B6 have different register offset than common rockhip pinmux, set the correct value for those pins in rk3328_mux_recalced_data. The pinmux bits for those 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, e.g. IO_SPIclkm0_GPIO2B0vccio5 with GRF_GPIO2B_IOMUX[1:0]=2'b01 setting. This fix has been tested on NanoPi R2S for fixing confliting pinmux bits between GPIO2-15 with GPIO2-13.
