hwmon (pmbus) use simple i2c probe function
pmbus_do_probe doesn't use the id information provided in its second argument, so this can be removed, which then allows using the single-parameter i2c probe function ("probe_new") for probes. This avoids scanning the identifier tables during probes. Drivers which didn't use the id are converted as-is; drivers which did are modified as follows: * if the information in i2c_client is sufficient, that's used instead (client->name); * configured v. probed comparisons are performed by comparing the configured name to the detected name, instead of the ids; this involves strcmp but is still cheaper than comparing all the device names when scanning the tables; * anything else is handled by calling i2c_match_id() with the same level of error-handling (if any) as before. Additionally, the mismatch message in the ltc2978 driver is adjusted so that it no longer assumes that the driver_data is an index into ltc2978_id.
