spi: spi-fsl-dspi: Fix issue with uninitialized dma_slave_config
[ Upstream commit 209ab223ad5b18e437289235e3bde12593b94ac4 ]
Depending on the DMA driver being used, the struct dma_slave_config may
need to be initialized to zero for the unused data.
For example, we have three DMA drivers using src_port_window_size and
dst_port_window_size. If these are left uninitialized, it can cause DMA
failures.
For spi-fsl-dspi, this is probably not currently an issue but is still
good to fix though.
