Revision 2 is SW compatible with revision 1 but it is necessary to reflect
it in model and compatible properties which are parsed by user space.
Rev 2 has improved a power on boot reset and MIO34 shutdown glich
improvement done via an additional filter in the GreenPak chip.

Changes in v2:
- Support older combinations
I want to support all versions we created:
All of them:
-rev2, -rev1, -revB, -revA, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
rev1:
-rev1, -revB, -revA, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
revB:
-revB, -revA, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
revA:
-revA, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
And also single one are permitted:
-revB, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
-rev1, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
-rev2, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
I didn't find a way to pretty much all the time force that there must be
both "xlnx,zynqmp-smk-k26", "xlnx,zynqmp" that's why there is only
requested to have xlnx,zynqmp. If you find a way how to encode it please
let me know.

This allows:
xlnx,zynqmp-sm-k26-rev2, foo, xlnx,zynqmp, bar
You need the schema form of 'items' (no '-'). For multiple contains, you
need 'allOf'. Like this:
items:
enum: [ all of them ]
allOf:
- contains:
const: xlnx,zynqmp
- contains:
const: xlnx,zynqmp-sm-k26
This of course has no enforcement of the order. Just no sane way to do
that in json-schema.

Works for me. If below is fine I will send v3 version.
