hwmon: (lm78) Remove use of i2c_match_id()
The function i2c_match_id() is used to fetch the matching ID from
the i2c_device_id table. This is often used to then retrieve the
matching driver_data. This can be done in one step with the helper
i2c_get_match_data().
This helper has a couple other benefits:
* It doesn't need the i2c_device_id passed in so we do not need
to have that forward declared, allowing us to remove those or
move the i2c_device_id table down to its more natural spot
with the other module info.
* It also checks for device match data, which allows for OF and
ACPI based probing. That means we do not have to manually check
those first and can remove those checks.
