spi: dw: Enable interrupts in accordance with DMA xfer mode
[ Upstream commit 43dba9f3f98c2b184a19f856f06fe22817bfd9e0 ]
It's pointless to track the Tx overrun interrupts if Rx-only SPI
transfer is issued. Similarly there is no need in handling the Rx
overrun/underrun interrupts if Tx-only SPI transfer is executed.
So lets unmask the interrupts only if corresponding SPI
transactions are implied.
