#1649208 — [PATCH] ARM: dts: rockchip:remove hs200 support for firefly reload

due to layout limitation. not all of the reload board can support hs200.
so remove hs200 support to make all board can boot up.

You now also remove DDR52, so all reload boards run at high speed mode?

I'm curious about what was the layout limitation that mmc tuning
process could never help?
