habanalabs: preboot hard reset support

FW hard reset capability indication is now moved to preboot stage.
Driver will check if HW is dirty only after it validated preboot
is up. If HW is dirty, driver will perform a hard reset according
to the FW capability.
In addition, FW defines a new message which driver need to send in
order to initiate a hard reset.
