These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

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.

CONFIG_SENSORS_XDPE122_REGULATOR is disabled
0-day reports:
drivers/hwmon/pmbus/xdpe12284.c:127:36: warning:
unused variable 'xdpe122_reg_desc'
This is seen if CONFIG_SENSORS_XDPE122_REGULATOR is not enabled.
Mark xdpe122_reg_desc as __maybe_unused to fix the problem.

Add support for another Infineon Multi-phase controller chip. The
xdpe11280 uses linear instead of vid data format for VOUT. Detect
VOUT_MODE format during identification and skip the xdpe122 related
adaptions in case it is linear.

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

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.

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.

In preparation for multi-phase support, add 'phase' parameter to read_word
and set_page functions. Actual multi-phase support will be added in
a subsequent patch.

Provide read_word_data() callback for overvoltage and undervoltage
output readouts conversion. These registers are presented in
'slinear11' format, while default conversion for 'vout' class for the
devices is 'vid'. It is resulted in wrong conversion in pmbus_reg2data()
for in{3-4}_lcrit and in{3-4}_crit attributes.

All these device support two pages.
The below lists of VOUT_MODE command readout with their related VID
protocols, Digital to Analog Converter steps, supported by these
devices:
VR12.0 mode, 5-mV DAC - 0x01;
VR12.5 mode, 10-mV DAC - 0x02;
IMVP9 mode, 5-mV DAC - 0x03;
AMD mode 6.25mV - 0x10.
