[PATCH v2 2/3] hwmon: (pmbus/isl68137) Add support for Renesas RAA228942 and RAA228943

[Dawei Liu]

Both RAA228942 and RAA228943 are digital dual-output 16-Phase
(X+Y <= 16) PWM controllers. They are PMBus command compatible
with the RAA228228/RAA228244/RAA228246 family and use the same
2-rail non-TC driver configuration.
