The HWMON_CHANNEL_INFO macro simplifies the code, reduces the likelihood
of errors, and makes the code easier to read.
The conversion was done automatically with coccinelle. The semantic patch
used to make this change is as follows.

This patch does not introduce functional changes. Many thanks to
Julia Lawall for providing the semantic patch.

In case an under-voltage happens before probing the driver wont
write the critical warning into the kernel log. So don't init
of last_throttled during probe and fix this issue.

The raspberrypi-hwmon driver doesn't automatically load, although it does work
when loaded, by adding the alias it auto loads as expected when built as a
module. Tested on RPi2/RPi3 on 32 bit kernel and RPi3B+ on aarch64 with
Fedora 28 and a patched 4.18 RC kernel.

Currently there is no easy way to detect undervoltage conditions on a
remote Raspberry Pi. This hwmon driver retrieves the state of the
undervoltage sensor via mailbox interface. The handling based on
Noralf's modifications to the downstream firmware driver. In case of
an undervoltage condition only an entry is written to the kernel log.
