AnalogController: Reset state on analog->digital switch

But only when the game does not support analog mode.

Tomb Raider's game selector menu puts the controller into
configuration mode, and we're supposed to respond with a
0x00 header byte if the user switches the pad to digital
mode.

Problem is, the game itself doesn't understand this mode
switch nor configuration mode. So the status byte gets
stuck at 0x00 if the user toggles analog mode, and the
game thinks no pad is connected.

Work around this by resetting the whole state if the game
does not support analog mode.
