Vijaya Krishna Nivarthi 1ec7096910 dmaengine: qcom: gpi: Set link_rx bit on GO TRE for rx operation

[ Upstream commit 25e8ac233d24051e2c4ff64c34f60609b0988568 ]

Rx operation on SPI GSI DMA is currently not working.
As per GSI spec, link_rx bit is to be set on GO TRE on tx
channel whenever there is going to be a DMA TRE on rx
channel. This is currently set for duplex operation only.

Set the bit for rx operation as well.
This is part of changes required to bring up Rx.
