Enable support for EL3 interrupt in IMF
This patch enables support for EL3 interrupts in the Interrupt Management
Framework (IMF) of ARM Trusted Firmware. Please note that although the
registration of the EL3 interrupt type is now supported, it has not been
tested on any of the ARM Standard platforms.
