spi: dw: Zero DMA Tx and Rx configurations on stack
[ Upstream commit 3cb97e223d277f84171cc4ccecab31e08b2ee7b5 ]
Some DMA controller drivers do not tolerate non-zero values in
the DMA configuration structures. Zero them to avoid issues with
such DMA controller drivers. Even despite above this is a good
practice per se.
