Re: [U-Boot] [U-Boot, 09/13] rockchip: dts: set fifo mode as default for mmc

[Philipp Tomsich]

This would be a change from the upstream DTSI file in Linux, which we
should try to avoid if possible.

Please handle this the same way as in Linux and fall back to fifo-mode
based on the transfer-mode bits [17:16] in HCON.

rk3066 and rk3188 designware mmc ip doesn't support internal dma
transfer mode. So set fifo mode as default.
