Data transfer mode is fixed by TrustZone (TZ), which currently restricts
developers from modifying the transfer mode from the APPS side.

Document the 'qcom,gsi-dma-allowed' property to select the data transfer
mode to GPI DMA (Generic Packet Interface). If not set, FIFO mode
(PIO/CPU DMA) will be selected by default.
