	  Enable support for the QCOM GPI DMA controller. This controller

	  provides DMA capabilities for a variety of peripheral buses such

	  as I2C, UART, and SPI. By using GPI dmaengine driver, bus drivers

	  can use a standardize interface that is protocol independent to

	  transfer data between DDR and peripheral.
