There was a misalignment between Zephyr UART device numbering and SoC UART IP. Device "UART_1" was mapped to IP USART_2, which could be confusing for user. This commit allows to align "UART_1" to IP USART_1. Change is propagated to all STM32F103RB/STM32F401RE based boards and respective pinmux drivers Change-Id: Ia8099dfeec7b9c0c686c2a58ccb4dbb1a55b6537 Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>
