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 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

dmaengine: add peripheral configuration
dmaengine: qcom: Add GPI dma driver
