tee: allow a driver to allocate a tee_device without a pool

Browse Source 
[ Upstream commit 6dbcd5a9ab ]

A TEE driver doesn't always need to provide a pool if it doesn't
support memory sharing ioctls and can allocate memory for TEE
messages in another way. Although this is mentioned in the
documentation for tee_device_alloc(), it is not handled correctly.
