hwmon: (pmbus/ibm-cffps) 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 another benefit:
* It also checks for device match data, which allows for OF based
probing. That means we do not have to manually check those first
and can remove that check.
As i2c_get_match_data() return NULL/0 on failure which also matches
the enum for "cffps1", switch around the enum order so cffps_unknown
is index 0 and existing behavior is preserved.
