This patch introduces new attribute OPTEE_MSG_ATTR_NONCONTIG to allow
Normal World pass arbitrary list of physical pages as a shared buffer.
To read this list of page address two new functions are added:
- msg_param_extract_pages() is a helper function that read pages list
into provided array
- msg_param_mobj_from_noncontig_param() constructs mobj from provided
struct optee_msg_param parameter. This mobj then can be used in
various parts of OP-TEE
