pinctrl: meson: fix uart_ao_b for GXBB and GXL/GXM
The GXBB and GXL/GXM pinctrl drivers had a configuration which conflicts with uart_ao_a. According to the GXBB ("S905") datasheet the AO UART functions are: - GPIOAO_0: Func1 = UART_TX_AO_A (bit 12), Func2 = UART_TX_AO_B (bit 26) - GPIOAO_1: Func1 = UART_RX_AO_A (bit 11), Func2 = UART_RX_AO_B (bit 25) - GPIOAO_4: Func2 = UART_TX_AO_B (bit 24) - GPIOAO_5: Func2 = UART_RX_AO_B (bit 25) The existing definition for uart_AO_A already uses GPIOAO_0 and GPIOAO_1. The old definition of uart_AO_B however was broken, as it used GPIOAO_0 for TX (which would be fine) and two pins (GPIOAO_1 and GPIOAO_5) for RX (which does not make any sense). This fixes the uart_AO_B configuration by moving it to GPIOAO_4 and GPIOAO_5 (it would be possible to use GPIOAO_0 and GPIOAO_1 in theory, but all existing hardware uses uart_AO_A there). The fix for GXBB and GXL/GXM is identical since it seems that these specific pins are identical on both SoC variants.
