hwmon: Support set_trips() of thermal device ops

Support set_trips() callback of thermal device ops. This allows HWMON
device to operatively notify thermal core about temperature changes, which
is very handy to have in a case where HWMON sensor is used by CPU thermal
zone that performs passive cooling and emergency shutdown on overheat.
Thermal core will be able to react faster to temperature changes.

The set_trips() callback is entirely optional. If HWMON sensor doesn't
support setting thermal trips, then the callback is a NO-OP. The dummy
callback has no effect on the thermal core. The temperature trips are
either complement the temperature polling mechanism of thermal core or
replace the polling if sensor can set the trips and polling is disabled
by a particular device in a device-tree.

Merge tag 'hwmon-for-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging

Pull hwmon updates from Guenter Roeck:
"The most notable change is the removal of the amd_energy driver. It
was rendered all but unusable by making its attributes privileged-only
to work around a security issue. A suggested remedy was rejected by
AMD, so the only real solution was to remove the driver. For the
future, we'll have to make sure that no privileged-access-only drivers
are accepted into the hwmon subsystem in the first place. The hwmon
ABI document was updated accordingly.

Other changes:

PMBus drivers:
- Added driver for MAX15301
- Added driver for BluTek BPA-RS600
- Added driver for fsp-3y PSUs and PDUs
- Added driver for Infineon IR36021
- Added driver for ST STPDDC60
- Added support for TI TPS53676 to tps53679 driver
- Introduced PMBUS symbol namespace. This was made necessary by a
suggestion to use its exported functions from outside the hwmon
subsystem.
- Minor improvements and bug fixes

New drivers:
- Driver for NZXT Kraken X42/X52/X62/X72

Driver enhancements:
- Added support for Intel D5005 to intel-m10-bmc-hwmon driver
- Added support for NCT6686D to nct6683 driver

Other:
- Converted sch5627 and amd9240 drivers to
hwmon_device_register_with_info()
- Added support for fan drawers capability and present registers to
mlxreg-fan driver
- Added Dell Latitude E7440 to fan control whitelist in dell-smm
driver
- Replaced snprintf in show functions with sysfs_emit. Done with
coccinelle script for all drivers to preempt endless per-driver
submissions of the same change.
- Use kobj_to_dev(). Another coccinelle based change to preempt
endless per-driver submissions of the same change.
- Various minor fixes and improvements"
