fix(bl31): pass the EA bit to 'delegate_sync_ea'

During a synchronous exception, the 'enter_lower_el_sync_ea' handler
tests the ESR_EL3 EA bit and calls 'report_unhandled_exception', if
it is not set.

EA = 0 and IFSC = SEA, seems to be a contradiction. EA provides further
classification of a synchronous abort. A synchronous abort is determined
by the IFSC value on an instruction fetch synchronous abort. As a result,
EA will never be set to 1 on an instruction fetch synchronous abort and
'report_unhandled_exception' should not be called.

This patch removes this behavior to allow the platform to handle the
exception.
