Subject: [PATCH v1 1/1] hwmon: (jc42) Drop of_match_ptr() protection

This prevents use of this driver with ACPI via PRP0001 and
is an example of an anti pattern I'm trying to remove from
the kernel. Hence drop from this driver.

Also switch of.h for mod_devicetable.h include given use of
struct of_device_id which is defined in that header.

Reported-by: Konstantin Aladyshev <aladyshev22@...il.com>
Closes: https://lore.kernel.org/r/CACSj6VW7WKv5tiAkLCvSujENJvXq1Mc7_7vtkQsRSz3JGY0i3Q@mail.gmail.com
