450d1a8ce1 hwmon: (pmbus/max16601) Add support for new revisions of MAX16508
New revisions of MAX16508 report MAX16508.xx or MAX16508y.xx as device ID,
but are functionally similar to MAX16508. Add support for those chip
variants.

1975d16786 hwmon: Switch i2c drivers back to use .probe()
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

From programming perspective, MAX16600 is identical to MAX16601 and
MAX16602. Add support for it.

Exported pmbus symbols are only supposed to be used from PMBus code.
Introduce PMBUS symbol namespace to prevent misuse from other code.

66102281f9 hwmon: (pmbus/max16601) Add support for MAX16508
MAX16508 is quite similar to MAX16601, except that it does not support
the DEFAULT_NUM_POP register and we thus can not dynamically determine
the number of populated phases.

3bce071a30 hwmon: (pmbus) shrink code and remove pmbus_do_remove()
The only action currently performed in pmbus_do_remove() is removing the
debugfs hierarchy. We can schedule a devm action at probe time and remove
pmbus_do_remove() entirely from all pmbus drivers.

dd43193976 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.
