arm64: zynqmp: Add support for K26 rev2 boards 



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.
