Series clk: clk-axiclgen: add support for ZynqMP | expand

Commit Message

The intent is to be able to run this driver to access the IP core in setups
where FPGA board is also connected via a PCIe bus. In such cases the number
of combinations explodes, where the host system can be an x86 with Xilinx
Zynq/ZynqMP/Microblaze board connected via PCIe.
Or even a ZynqMP board with a ZynqMP/Zynq/Microblaze connected via PCIe.

To accommodate for these cases, this change removes the limitation for this
driver to be compilable only on Zynq/Microblaze architectures.
And adds dependencies on the mechanisms required by the driver to work (OF
and HAS_IOMEM).

Make sense.
