From: Heiko Stuebner <heiko.stueb...@theobroma-systems.com>
Rockchips dwmmc controllers can't do dma to non-ddr addresses,
like for example the soc-internal sram but during boot parts of
TrustedFirmware need to be placed there from the read FIT image.
So add handling for a u-boot,spl-fifo-mode to not put the mmc
controllers into fifo mode for all time.
The regular fifo-mode property still takes precedent and only
if not set do we check for the spl-specific property.
