Pressing Fn+F10 on Acer Nitro 5 AN515-58 incorrectly triggers display
brightness down (scancode 0xef) instead of keyboard backlight control,
causing the screen to go completely dark. Similarly, Fn+F9 (scancode
0xf0) has no function explictily stated in hwdb causing unknown keycode
debug messages.
Both keys should control the keyboard backlight as labeled on the
keyboard. Map scancodes 0xef and 0xf0 to kbdillumup and kbdillumdown
respectively to enable proper keyboard backlight control.
