Add support for NXP's flexcomm usart. It supports interupts and FIFO access but no DMA. The patch includes an automatically generated header which contains the register layout and helpers. The header can be regenerated with the svd-flexcomm-usart target when the build is configured with --enable-mcux-soc-svd.
