plat-stm: support registered shm buffers

CFG_DDR_SECURE_BASE/_SIZE can be used to define the DDR range reserved
to secure side. This can be larger than the TEETZ reserved memory.
If CFG_DDR_SECURE_BASE/_SIZE is defined, plat-stm registers the
non-secure external memory to support dynamic shm registering.

core:sdp: fix SDP test pseudo-TA against dynamic shm

Physical memory typed CORE_MEM_NSEC_SHM belong to the default
contiguous shm memory. Since dynamic SHM, now non secure memory
reference can be outside the default NSEC_SHM, hence check
non secure reference using CORE_MEM_NON_SEC type instead of
CORE_MEM_NSEC_SHM.

core: enable non-contiguous temporary reference parameters

Now, when we can pass list of pages between REE and TEE it is possible
to use temporary memory references that are not located in a preallocated
shared memory area. By employing OPTEE_MSG_ATTR_NONCONTIG parameter
attribute, REE can provide own buffer as a temporary memory reference.

Actually, such parameters are indistinguishable from registered shared
memory references. So, when OP-TEE spots temporary memory reference with
OPTEE_MSG_ATTR_NONCONTIG attribute, it will create `mobj_reg_shm` for it.
After call was handled, it will free that mobj.
