target/arm: Allow deliver_fault() caller to specify EA bit

Browse source 
For external aborts, we will want to be able to specify the EA
(external abort type) bit in the syndrome field.  Allow callers of
deliver_fault() to do that by adding a field to ARMMMUFaultInfo which
we use when constructing the syndrome values.
