RAS: Introduce handler for Double Faults
Double fault is when the PE receives another error whilst one is being
handled. To detect double fault condition, a per-CPU flag is introduced
to track the status of error handling. The flag is checked/modified
while temporarily masking external aborts on the PE.
This patch routes double faults to a separate platform-defined handler.
