In order to register a shared buffer in TEE, we need accessor
function that return list of pages for that buffer.

We need to ensure that tee_context is present until last
shared buffer will be freed.

Now, when struct tee_shm is defined in public header,
we can inline small getter functions.

This is simple pool that uses kernel page allocator. This pool can be
used in case OP-TEE supports dynamic shared memory.

With latest changes to OP-TEE we can use any buffers as a shared memory.
Thus, it is possible for supplicant to provide part of own memory
when OP-TEE asks to allocate a shared buffer.
This patch adds support for such feature into RPC ha

Now, when client applications can register own shared buffers in OP-TEE,
we need to extend ABI for parameter passing to/from OP-TEE.
So, if OP-TEE core detects that parameter belongs to registered shared
memory, it will use corresponding par
