[PATCH v2 03/11] hwmon: (pmbus/isl68137) Remove use of i2c_match_id()

[Andrew Davis <afd@ti.com>]

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 that.
 * It also checks for device match data, which allows for OF and
   ACPI based probing.
