BL31: Add SDEI dispatcher · b7cb133e

Jeenu Viswambharan authored Oct 16, 2017

The implementation currently supports only interrupt-based SDEI events,
and supports all interfaces as defined by SDEI specification version

Introduce the build option SDEI_SUPPORT to include SDEI dispatcher in
BL31.

Update user guide and porting guide. SDEI documentation to follow.
