When CONFIG_HWMON is disabled, we currently get a link error for this driver:
ERROR: "hwmon_device_unregister" [drivers/misc/habanalabs/habanalabs.ko]
undefined!
ERROR: "hwmon_device_register_with_info"
[drivers/misc/habanalabs/habanalabs.ko] undefined!
As the hardware monitoring is not a required part of the functionality,
make it possible to compile without HWMON by ignoring all that functionality
depending on the configuration.
