drivers: spi_mcux_lpspi: Fix synchronous DMA CS
Fix the chip select when using the synchronous API with DMA path.
Note need to use TxDataRequest flag instead of ModuleBusy flag now
because module busy flag will not deassert until PCS deasserts.
This does not fix CS for the non-DMA path, because that would require a
large driver rework.
Do not skip configuration when calling transceive with the same spi_cfg
because we need to write a new command word.
