ipod: Support IAP remote MENU/SELECT/UP/DOWN keys in MODE2

Only the primary contexts (standard, wps, quckscreen, tree, radio)
handle the new keys so far.

Todo contexts:  Settings, keyboard, pitchscreen, bookmark, & recording.

Available docs for MODE4 don't list anything other than playback
controls, so it's not clear if there is a path forward here.
