B4860EMU is a emualtor target with minimum peripherals. It is based on
B4860QDS and trimmed down most peripherals due to either not modeled or
lack of board level connections. The main purpose of this minimum dts is
to speed up booting on emulator.

I did not give a reviewed-by in this context.  Please strip gerrit tags
before posting.

It's "fsl,qoriq-clockgen-2.0" now.

Please be careful with copy-and-paste patches like this -- make sure
that it's up-to-date with what you copied from.
