accel: Expose and register generic_handle_interrupt()

In order to dispatch over AccelOpsClass::handle_interrupt(),
we need it always defined, not calling a hidden handler under
the hood. Make AccelOpsClass::handle_interrupt() mandatory.
Expose generic_handle_interrupt() prototype and register it
for each accelerator.
