Whilst fairly unlikely anyone will ever use this driver with anything
other than DT, we are trying to move IIO over to the generic interfaces
where easy to do so.
In this case this involved moving to generic check on presence
of fwnode, generic device_get_match_data() and dropping the of_match_ptr
protection. Also relevant header changes to have property.h and
mod_devicetable.h only.
Also drop the casting away of a const in favour of retaining
the const throughout.

There is no real advantage in having these protections and
for parts that do not have an explicit ACPI ID, it prevents the
use of PRP0001. I'm trying to clear this out of IIO in general
to avoid copying in new drivers.
Include mod_devicetable.h as we are using of_device_id in here so
including that header is best practice.

This driver cannot be instantiated from ACPI due to it's use of
syscon_regmap_lookup_by_phandle() but in the interests of clearing
this anti pattern out of IIO, let us switch to an explicit
check in Kconfig and remove the protections on the of_match_table
The switch of header is because we only use of_device_id
in here and that is defined in mod_devicetable.h not of.h.

This driver has no built-in trigger. In order for making triggered
measurements, an external (software) trigger driver like
iio-trig-hrtimer or iio-trig-sysfs is required.
The sensor supports single and continuous measurement modes. The latter
is not used by design as this would require tight timing synchronization
between hardware and driver without much benefit.
