ARM: zynq: Add DTSes for mini qspi configurations
Mini U-Boot is running out of OCM and it's only purpose is to program non
volatile memories. There are different configurations which qspi can be
that's why describe them via DT.
DT binding is already approved that's why there is no reason not to add it.
