optee_shm_register() expected pages to be passed as an array of page
pointers rather than as an array of contiguous pages. So fix that via
correctly passing pages as per expectation.

In case of dynamic shared memory pool, kernel memory allocated using
dmabuf_mgr pool needs to be registered with OP-TEE prior to its usage
during optee_open_session() or optee_invoke_func().
So fix dmabuf_mgr pool allocations via an additional call to
optee_shm_register().
Also, allow kernel pages to be registered as shared memory with OP-TEE.
Fixes: 9733b072a12a ("optee: allow to work without static shared memory")

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