Introduce interrupt handling framework in BL3-1
This patch adds a common handler for FIQ and IRQ exceptions in the BL3-1 runtime exception vector table. This function determines the interrupt type and calls its handler. A crash is reported if an inconsistency in the interrupt management framework is detected. In the event of a spurious interrupt, execution resumes from the instruction where the interrupt was generated. This patch also removes 'cm_macros.S' as its contents have been moved to 'runtime_exceptions.S' Change-Id: I3c85ecf8eaf43a3fac429b119ed0bd706d2e2093
