sensor: accept single sensor threshold
Currently, sensors require a couple of LC/UC and/or LNC/UNC. However, in
real hardware design, there might be only one of LC, UC, LNC or UNC
available.
This change allows to specify only single sensor threshold.
Tested:
1. Specify only UC threshold for PSU0_Temp sensor
2. root@mtjade:~# ipmitool sensor get PSU0_TEMP
Locating sensor record...
Sensor ID : PSU0_TEMP (0xf3)
Entity ID : 30.58
Sensor Type (Threshold) : Temperature
Sensor Reading : 26 (+/- 0) degrees C
Status : ok
Lower Non-Recoverable : na
Lower Critical : na

Upper Non-Critical : na
Upper Critical : 64.000
Upper Non-Recoverable : na
Positive Hysteresis : Unspecified

Exposes generic hwmon entries as DBus objects. More information can be found at Sensor Architecture
To build this package, do the following steps:
1. meson build
2. ninja -C build
To clean the repository run `rm -rf build`.
To enable the use of Linux features like cgroups prioritization and udev/systemd control, one instance of phosphor-hwmon is intended to be run per hwmon sysfs class instance. This requires an algorithm for selecting a stable, well-known D-Bus busname. The algorithm is <PREFIX>-<ID>.Hwmon<N> where PREFIX is an autoconf configurable prefix (BUSNAME_PREFIX, xyz.openbmc_project by default), ID is either a std::hash of the /sys/devices path backing the hwmon class instance or provided suffix value from the command line, and N is the implemented phosphor-hwmon D-Bus API version.
