Add LPUART1 as a standard UART. No low power features are supported, yet. LPUART1 is enabled as the next available UART after the standard U(S)ARTs: STM32WB: LPUART1 = UART(2) STM32L0: LPUART1 = UART(6) STM32L4: LPUART1 = UART(6) STM32H7: LPUART1 = UART(9) On all ports: LPUART1 = machine.UART('LP1') LPUART1 is enabled by defining MICROPY_HW_LPUART1_TX and MICROPY_HW_LPUART1_RX in mpconfigboard.h.
