UpKbdBacklight: Send notifications about hardware brightness changes
Backlights, starting with kernel 4.11 [1] can have a
"brightness_hw_changed" sysfs attribute, which can be polled to detect
hardware initiated brightness changes, such as ones done through
firmware-handled keyboard backlight hotkeys, or firmware controlled
changes (eg. turn off backlight on low battery).
