clk: axi-clkgen: replace ARCH dependencies with driver deps

Browse source 
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).

Support for the Analog Devices axi-clkgen pcore clock generator for Xilinx
FPGAs. It is commonly used in Analog Devices' reference designs.
