msi-laptop: send out touchpad on/off key

MSI BIOS's raw behavior is send out KEY_TOUCHPAD_TOGGLE key when user
pressed touchpad hotkey.

Actually, we can capture the real touchpad status by read 0xE4 EC address
on MSI netbook/notebook. So, add msi-laptop input device for send out
KEY_TOUCHPAD_ON or KEY_TOUCHPAD_OFF key when user pressed Fn+F3 touchpad
hotkey. It leave userland applications to know the real touchpad status.

Tested on MSI netbook U-100, U-115, U160(N051), U160DX, N014, N034
Tested on MSI notebook CR620
