Add the EARLY_PD_DOWN state to the set of possible states for a PD. The PD will enter this state and send an indication to the HLOS shortly before sending the PD_DOWN indication. This indication does not require an ACK back, unlike the PD_[UP/DOWN] indication. This indication is sent when PD dumps are collected, and before a PD dies. Any memory that is part of the PD dumps should not be unmapped as part of the handling for this indication, as it may be used during the PD dump collection.
