KVM: arm64: Route SEAs to the SError vector when EASE is set
One of the finest additions of FEAT_DoubleFault2 is the ability for
software to request *synchronous* external aborts be taken to the
SError vector, which of coure are *asynchronous* in nature.
Opinions be damned, implement the architecture and send SEAs to the
SError vector if EASE is set for the target context.
