This series adds support for Qcom GSI dma controller found on Qualcomm SoCs.
This controller can program the peripheral configuration so we add
additional parameters in dma_slave_config for configuring the peripherals
like spi and i2c.

Changes in v5:
 - Add acked by Rob
 - Move qcom-gpi-dma.h header to include/linux/dma/
 - rebase and test on v5.10-rc2

Changes in v3:
 - Update the i2c tre creation based on testing feedback

Changes in v2:
 - Update the binding and drop qcom specific properties
 - Move peripheral configuration as a pointer
 - Move submit queue for transactions to issue_pending
