platform/x86: fujitsu-laptop: Support Lifebook S2110 hotkeys

[ Upstream commit a7e255ff9fe4d9b8b902023aaf5b7a673786bb50 ]

The S2110 has an additional set of media playback control keys enabled
by a hardware toggle button that switches the keys between "Application"
and "Player" modes. Toggling "Player" mode just shifts the scancode of
each hotkey up by 4.

Add defines for new scancodes, and a keymap and dmi id for the S2110.

Tested on a Fujitsu Lifebook S2110.
