This patch is in preparation for VM to VM support in order to do the
changes on the SP handling part of partinfo_get before adding support
for the VM part.
This patches is doing the following changes:
- split partinfo_get into 3 functions to have the locking handling and
proper exit on error handled more clearly
- add some potential overflow checks to validate the offset and sizes
passed by the VM on partinfo call.
- Introduce a maximum number of SPs (for now set to 64) to prevent
holding the CPU for too long in case there would be a lot of
partitions in the secure world. The limit currently set is thought to
be realistic for most use cases as 64 secure partitions is a very high
number compared to current seen usage (more 3 or 4).
- fix include ordering in ffa_private.h to be in alphabetic order
