Converted the mmio_flip 'seqno' value to be a request structure as part of the on going seqno to request changes. This includes reference counting the request being saved away to ensure it can not be retired and freed while the flip code is still waiting on it. v2: Used the IRQ friendly request dereference call in the notify handler as that code is called asynchronously without holding any useful mutex locks.
