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.
