hwmon: (tmp108) Drop of_match_ptr() protection

hwmon: (tmp108) Drop of_match_ptr() protection

Limiting the scope of devicetree support to CONFIG_OF prevents use of this
driver with ACPI via PRP0001. Drop the dependency.

While at it,
- Switch of.h for mod_devicetable.h include given the use of struct
  of_device_id which is defined in that header
- Add I2C device ID for p3t1085
- Drop the unnecessary include of hwmon-sysfs.h.
