The dwmmc controllers on rk3188 do not have idma support, so need to
use the fifo-mode and it my tests they became confused and stopped
working if the frequency was to high.
While I only tested in somewhat bigger steps, 32MHz for example
hung the controller, while reducing it to 16MHz worked just fine
and is reasonably fast to load a kernel from mmc.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Add dts node for timer3.
Because of the rockchip timer can only KNOWN "dtd_rockchip_rk3368_timer"
with OF_PLATDATA enable, so we override its compatible to
"rockchip,rk3368-timer".
