Use the same prop as linux to control the use of fifo or dma mode. Also
add a u-boot,spl-sfc-no-dma prop to control the same in SPL.

f0d49d4f0d spi: rockchip_sfc: Add missing include for dm/device_compat.h
Add missing include for dm/device_compat.h. Without this include the
SFC driver fails to compile because dev_err and dev_dbg are not
defined.

3fb08a2138 spi: rockchip_sfc: add support for Rockchip SFC
This patch adds support for the Rockchip serial flash controller
found on the PX30 SoC. It should work for versions 3-5 of the SFC
IP, however I am only able to test it on v3.

This is adapted from the WIP SPI-MEM driver for the SFC on mainline
Linux. Note that the main difference between this and earlier versions
of the driver is that this one does not support DMA. In testing
the performance difference (performing a dual mode read on a 128Mb
chip) is negligible. DMA, if used, must also be disabled in SPL
mode when using A-TF anyway.
