Add the MP5998 power monitor device on I2C bus with address 0x46
for the Yosemite5 platform.

This allows the hwmon driver to probe the device and expose the
power monitoring telemetry to userspace.

I would rather you describe the purpose of the power monitoring. Why is
this instance of an MP5998 necessary in the system design? The address
of the sensor is evident from the details in the patch and isn't
necessary to describe here.

I would prefer you reword or remove this sentence. The purpose of the
devicetree is to describe the hardware. What the firmware/kernel
chooses to do with that information is a separate problem.
