Since the raspberrypi-hwmon driver is tied to the VC4 firmware instead of
particular hardware its registration should be in the firmware driver.

A common issue for the Raspberry Pi is an inadequate power supply.
Noralf Trønnes started a discussion [1] about writing such undervoltage
conditions into the kernel log.
This series is a draft to upstream the resulting kernel patch and is not
intended for 4.18.
Changes in V2:
- simplified Kconf
Recent Raspberry Pi firmware provides a mailbox property to detect
under-voltage conditions. Here is the current definition.
The u32 value returned by the firmware is divided into 2 parts:
- lower 16-bits are the live value
- upper 16-bits are the history or sticky value
Bits:
