ideapad: add event for Novo key
Novo key is the Lenovo define key on every ideapads, which has two definition. Long press and short click. Driver will report KEY_PROG1 on short click and KEY_PROG2 when long press. On pre-install OS for ideapads there are application waiting for the event and there is no such application for Linux yet, so I think to report KEY_PROG is fine in anyway. Also change the scancode from hex to decimal because they are related to vpc bit in notify function which is in decimal.
