Add Device Tree compatible strings for Renesas RAA229639 and
RAA229640 PMBus devices.

A fallback compatible is not introduced because the available
documentation does not establish DT-level compatibility with
any existing supported device.

From: Colin Huang <redacted>

Add support for the Renesas RAA229639 and RAA229640 PMBus
voltage regulator devices.

Both devices are supported by the existing raa_dmpvr2_2rail
driver variant, so no functional changes are required beyond
adding the corresponding device IDs and OF match entries.

commit 1702c94b50317002cdd0b95f06c65c3af4214d35
Author: Colin Huang [off-list ref]

hwmon: (pmbus/isl68137): Add Renesas RAA229639 and RAA229640

This commit adds support for the Renesas RAA229639 and RAA229640 PMBus
voltage regulator devices. It updates the existing raa_dmpvr2_2rail driver
variant by adding the corresponding device IDs and OF match entries.

[Severity: Low]
Since these new devices are being added to the driver, should they also be
documented in the "Supported chips" list within
Documentation/hwmon/isl68137.rst alongside the existing parts?

Please don't respin before people have a chance to actually respond to
the thread. Please see my commentary on V(this - 1) on the compatiblity
of the devices being added.
