BL31: Add SDEI dispatcher
The implementation currently supports only interrupt-based SDEI events,
and supports all interfaces as defined by SDEI specification version
1.0 [1].
Introduce the build option SDEI_SUPPORT to include SDEI dispatcher in
BL31.
Update user guide and porting guide. SDEI documentation to follow.
