During the interrupt registration comparison is made against max value of exception types for ARMV7, but in the common handling function the check is made against max value of exceptions types for ARMV8. This can lead to undefined behaviour during registration of interrupts. This patch modifies the registration function to handle only AArch64 exceptions.
