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.

Umhhh ... no dependencies? How are you accessing your registers? You
seem to be using device tree, probably:

	depends on HAS_IOMEM || COMPILE_TEST
	depends on OF

at least? Please double check your dependencies.

Agreed.
Will re-spin.
This is a n00b mistake on my part
