    evdev: map ChromeOS "Vivaldi" top-row action keys
    
    Chromebook keyboards driven by the ChromeOS EC emit the top-row action
    keys as scancode set 1 codes 0xE0 0x11 - 0xE0 0x1E (see the codeset 1
    comments on the SCANCODE_* enum in chrome-ec
    include/keyboard_8042_sharedlib.h).  The e0 half of the
    evdev_scancode2key() translation table leaves eleven of those at NONE,
    so on FreeBSD those keys emit no evdev event at all and userspace
    remappers such as keyd have nothing to bind to:
    
      e0 11  fullscreen             KEY_ZOOM
      e0 12  overview               KEY_SCALE
      e0 13  screenshot             KEY_SYSRQ
      e0 14  brightness down        KEY_BRIGHTNESSDOWN
      e0 15  brightness up          KEY_BRIGHTNESSUP
      e0 16  privacy screen toggle  KEY_PRIVACY_SCREEN_TOGGLE
      e0 17  kbd backlight down     KEY_KBDILLUMDOWN
      e0 18  kbd backlight up       KEY_KBDILLUMUP
      e0 1a  play/pause             KEY_PLAYPAUSE
      e0 1b  mic mute               KEY_MICMUTE
      e0 1e  kbd backlight toggle   KEY_KBDILLUMTOGGLE
    
    Fill those in.  Only entries that were previously NONE are touched: the
    EC's remaining top-row codes already have mappings here (e0 10 prev
    track, e0 19 next track, e0 20 mute, e0 2e / e0 30 volume, e0 67 refresh,
    e0 69 forward, e0 6a back), as do e0 1c keypad enter and e0 1d right
    control, and none of them change.
