spi: spi-fsl-dspi: Reset SR flags before sending a new message 
If, in a previous transfer, the controller sends more data than expected
by the DSPI target, SR.RFDF (RX FIFO is not empty) will remain asserted.
When flushing the FIFOs at the beginning of a new transfer (writing 1
into MCR.CLR_TXF and MCR.CLR_RXF), SR.RFDF should also be cleared.
Otherwise, when running in target mode with DMA, if SR.RFDF remains
asserted, the DMA callback will be fired before the controller sends any
data.

Take this opportunity to reset all Status Register fields.

Fixes: 5ce3cc5674 ("spi: spi-fsl-dspi: Provide support for DSPI slave mode operation (Vybryd vf610)")
