With CFG_CORE_DYN_PROTMEM=y support dynamic protected memory lending.
A new internal struct mobj_ffa_rsm is added to handle dynamic protected
memory for FF-A.
A new internal struct mobj_protmem is add to handle dynamic protected
memory without FF-A.
Lending non-secure memory to OP-TEE to use it as protected memory means
that it should to become inaccessible by the normal world as part of the
process. This part is currently not supported, since it must be done in
a platform specific way for platforms that support that. QEMU don't
support that.
Adding two platform specific functions, plat_get_protmem_config() and
plat_set_protmem_range() for dynamic protected memory. The functions has
__weak implementation to allow easier testing. However,
plat_set_protmem_range() requires CFG_INSECURE=y since it doesn't change
memory protection.
