This patch updates the LS2080a simulator DTS to add support of various
peripherals which are supported on the simulator platform and explicitly
disables those which are yet not supported on the platform.

The more common way to do this is to turn off all optional HW blocks in the
.dtsi file and then overide the ones that are connected on a particular board
by overriding the status to "ok" there.

I kind of remember it the other way around. But this will not be a huge change,
so will address it in v4.
