From: Achin Gupta <achin.gupta@arm.com>
With FF-A v1.1, the SPMC sends a reduced amount of boot information as
compared to the original SPM implementation. For example, the stack layout,
MP information etc. This information could be accommodated in the old data
structure but this is too complicated. This patch defines a new structure
to clearly separate FF-A v1.1 and other functionality.
