The EDKII/StandaloneMm module runs as a S-EL0 partition
on top of the EL3 FF-A SPMC.
In the past the StandaloneMm partition received its boot information through
the use of a device tree (DT) passed through the FF-A boot protocol.
The StandaloneMm itself converted the DT into a HOB.
To better match the UEFI PI spec,
the EL3 SPMC must now produce the HOB including the PHIT
(Phase Handoff Information Table) as first item in the HOB list.
The SPMC then passes the HOB through the FF-A boot protocol for
the StandaloneMm consumption.
This discards the use of a DT between the SPMC and
the StandaloneMm partition.
