platform/x86: lg-laptop: Add support for additional events

Browse Source 
Newer devices support a number of additional events:
- 0x0: Placeholder event
- 0x78: Mute audio
- 0xf070002: Open settings
- 0x30010000/0x30010001: Hotkey combination pressed/released
- 0x40020000: Disable camera
- 0x40020001: Mute microphone
- 0x40030001: Fn-lock

Map those events onto appropriate key codes.
