hwmon: (pmbus/isl68137) Add support for Renesas RAA228942 and RAA228943

Add I2C device IDs for Renesas RAA228942 and RAA228943.

At the Linux PMBus hwmon interface level currently supported by this
driver, these devices are compatible with the existing 2-rail non-TC
controllers, so devicetree will use fallback compatibles and no
dedicated OF match entries are needed.
