    boards/arm/stm32l4/nucleo-l432kc/Kconfig:  Correct use of spaces instead of TABs in Kconfig file.

Author: Pieter du Preez <wingunder@users.noreply.github.com>

    Added Kconfig pin config chooser for nucleo-l432kc USARTs. (#11)

    The USART pins were hard-coded for the nucleo-l432kc. This patch makes
    these pins configurable via menuconfig.
