spi: imx: use prepare_transfer_hardware() for lpspi The old driver enable clk in fsl_lpspi_prepare_message() and disable clk in fsl_lpspi_unprepare_message(). Rather than doing this per message it's a bit better to do it in prepare_transfer_hardware(), that way if there's a sequence of messages queued one after another we don't turn the clock on and off all the time.
