Convert the module to be property provider agnostic and allow
it to be used on non-OF platforms.
Include mod_devicetable.h explicitly to replace the dropped of.h
which included mod_devicetable.h indirectly.

Thanks Andy,
Applied this to the togreg-cleanup branch of iio.git.
I wondered whether there were any users of the platform_data /
board file path left. Seems that the support for the parent mfd
platform data was ripped out by Uwe in 2022 but not the sub drivers.
Anyone want to do the work to drop it from here and the other sub drivers?
