Create generic FF-A SP environment
Currently the boot method of SPs is SPMC specific. Each SPMC uses a
different binary format and different boot method. An SPMC agonistic
binary format and boot method has been defined, to remove
fragmentation. This is called "generic FF-A SP" here. All SPMC
implementations developed or contributed by Arm will add support for
this format. This change adds a new environment to capture the SPMC
independent binary format and boot method specifics.
