quark: Introduce Quark Secure Partition

Test partition designed to have a virtual address space as small as
possible in order to test the extension ARMv8.4-TTST. This Secure
Partition doesn't have print capabilities. The only service it provides
is one that returns a magic number to verify that it has been loaded.
