SPM: Register Secure Partition priority level with ehf module
Register a priority level, PLAT_SP_PRI, for secure partition with EL3
exception handling framework(ehf) module.
The secure partition manager(SPM) would raise the core's priority to
PLAT_SP_PRI before entering the secure partition, to protect the core
from getting interrupted while in secure partition.
