At present, both SDEI_PRIVATE_RESET and SDEI_SHARED_RESET returns
SDEI_PENDING if they fail to unregister an event. The SDEI specification
however requires that the APIs return SDEI_EDENY in these cases. This
patch fixes the return codes for the reset APIs.

The SDEI specification requires that binding a client interrupt
dispatches SDEI Normal priority event. This means that dynamic events
can't have Critical priority. Add asserts for this.

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.
