net: phy: aquantia: add hwmon support
This adds HWMON support for the temperature sensor and the related
alarms on the 107/108/109 chips. This patch is based on work from
Nikita and Andrew. I added:
- support for changing alarm thresholds via sysfs
- move HWMON code to a separate source file to improve maintainability
- smaller changes like using IS_REACHABLE instead of ifdef
(avoids problems if PHY driver is built in and HWMON is a module)
v2:
- remove struct aqr_priv
- rename header file to aquantia.h
v3:
- add conditional compiling of aquantia_hwmon.c
- improve converting sensor register values to/from long
- add helper aqr_hwmon_test_bit
