Pulls in updates in the internal headers from OP-TEE OS [1]. A few
defines has been shortened, hence the changes in rpc.c. Defines not used
by the driver in tee_rpc_cmd.h has been filtered out.
Note that this does not change the ABI.

TEE Client introduce a new capability "TEE_GEN_CAP_MEMREF_NULL"
to handle the support of the shared memory buffer with a NULL pointer.
This capability depends on TEE Capabilities and driver support.
Driver and TEE exchange capabilities at driver initialization.

In the OPTEE_SMC_CALL_GET_OS_REVISION request, the previously reserved
parameter a2 is now documented as being an optional build identifier
(such as an SCM revision or commit ID, for instance).
A new structure optee_smc_call_get_os_revision_result is introduced to
be used when querying the secure OS version, instead of re-using the
struct defined for OPTEE_SMC_CALLS_REVISION.

There were changes in REE<->OP-TEE ABI recently.
Now ABI allows us to pass non-contiguous memory buffers as list of
pages to OP-TEE. This can be achieved by using new parameter attribute
OPTEE_MSG_ATTR_NONCONTIG.
OP-TEE also is able to use all non-secure RAM for shared buffers. This
new capability is enabled with OPTEE_SMC_SEC_CAP_DYNAMIC_SHM flag.
This patch adds necessary definitions to the protocol definition files at
Linux side.
