rk3308: ddr: add uart0 loader

[angeloc]

Adding uart0 loader for boards with serial console on uart0 (Rock Pi s)

In the process of adding a Rock Pi S in buildroot, I noticed that i cannot run an x86 binary on the host because buildroot use host tools built from sources. Therefore I need to have the loader for uart0 already available as binary.

@angeloc how did you build this out of interest ?

[Yaksinikos]

I hve found a "RK30xxLoader(L)_V2.19.bin" on the net as well, would be nice to see it in the official repository, as well as a updated tools folder, at least rkdeveloptool, rkflashtool are out of date.

Nobody is interested, closing this PR

@angeloc Can you explain what you did to build the binary, in case others are interested in future?

@obbardc There is documentation about using the tools to change parameters here https://github.com/rockchip-linux/rkbin/blob/master/tools/ddrbin_tool_user_guide.txt
