FF-A: Booting SPs according to 'boot-order'
Secure Hafnium boots partitions according to boot-order in the manifest.
In this patch:
- Added manifest parsing of "boot-order", and populated VM structure
with it;
- Added the field "next_boot" to the VM structure, in order to create a
boot list that is sorted by the "boot-order";
- The root of the list points to the highest priority VM;
- Booting consists on traversing the list upon use of MSG_WAIT
interface from the highest priority VMs;
- After traversing the whole boot list, returns execution to SPMD;
- "manifest_Test.cc" updated to include "boot-order" field in
tests to the partition manifest;
- "vm_test.cc" updated to include unit test for the main logic of this
patch.
