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
