[U-Boot] [PATCH 2/4] rockchip: rk3308: enable spl-fifo-mode for emmc

[Andy Yan]

We need load some parts of ATF to sram, but rockchip
dwmmc controllers can't do dma to non-ddr addresses
space, so set the mmc controller into fifo mode in spl.

And show my best respect to Heiko's work for this solution.
