StandaloneMm/Library: Apply transfer list boot protocol in StandaloneMm
To remove hob creation in StandaloneMm entrypoint,
TF-A should pass PHIT hob information to StandaloneMm.
When it passes PHIT hob, it passes according to
firmware handoff specification[0].
This patch applies boot protocol using transfer list with firmware
handoff specification and remove hob creation in StandaloneMm
entrypoint.
