dmaengine: gpi: add GPI dmaengine driver snapshot 



This change ports GPI dmaengine driver and its dependencies
from msm-4.14 to msm-4.19. All the files are as is from
msm-4.14. Additional changes were made to gpi driver to
support 4.19 kernel.

This gpi dmaengine driver snapshot is taken as of msm-4.14

          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.
