arm/rockchip.yaml - many separate entries instead of enums

that was the original intention in doing it this way, preserving the
normal readability while adding machine readability to it :-)

I do like the current way as it does only contains one way of doing it.

As far as I can see, the fsl one has multiple types, like the one you
pointed at, for a list of boards + one soc that works for the simple
plethora of regular boards.

But also additional types that do it similarly to Rockchip like the 
	"i.MX6Q Advantech DMS-BA16 boards"
directly below it.


As we have both cases here as well, I really don't like this mix
but instead really like to have only one approach, hence the
one-entry-per-board-family we do in rockchip.yaml [2]

For human readability I really do consider having _one_ way
of describing boards superior to mixing approaches and the
automated parsing doesn't care, as long as the syntax is correct ;-)
