drivers: spi_mcux_lpspi: add support dma per instance

Currently, the driver imply understand that all instances
will use dma when CONFIG_SPI_MCUX_LPSPI_DMA is set. There
might be an instance doesn't need DMA, so instead of enforce
spi_transceive API to use DMA, add more flexible to enable
DMA only when required
