core: allow SDP buffers as memory reference parameters

Before this change, at OP-TEE entry (from non secure), memory
reference parameters needed to match the 'shm_mobj': the nonsecure
shared memory.

This change allows memory reference parameters to match the
registered SDP memories and be used when invoking TA that
claimed the SDP support through TA_FLAG_SECURE_DATA_PATH.

As SDP memory is not default mapped in OP-TEE core, nonsecure cannot
invoke a pseudo/static TA with a SDP memref parameter. only a user TA
can invoke a pseudo/static TA with a SDP memref parameter.

core: platform registers SDP memories

Secure data path support is conditioned to CFG_SECURE_DATA_PATH.

Core statically defines the SDP shared memory objects through macro
register_sdp_shm().

Configuration directives CFG_TEE_SDP_SHM_BASE/_SIZE allow to register
a "default" SDP memory area from generic implementation.

SDP memories are not default map in OP-TEE core hence locations
are not tested against OP-TEE memory layout. This change verifies
the SDP memories layout against OP-TEE memory mapping memory. This
is mandatory to prevent false identification of memory references
if referring only to the list of the registered SDP memories when
identifying a memory reference (later changes for SDP support).
