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'
