feat(plat/qemu): add sdei support for QEMU

Browse source 
Add sdei support for QEMU, this is to let jailhouse Hypervisor
use SDEI to do hypervisor management, after physical IRQ
has been disabled routing.

Note: To enable SDEI in QEMU, it needs to set "SDEI_SUPPORT=1
EL3_EXCEPTION_HANDLING=1" when compiling.
