Please pull these tee driver changes. This fixes a a problem with
determining the max device id value for the privileged device. This is
only a problem if there's more than 16 tee devices registered. There's
also added support to report OP-TEE revision information.

Adds helpers to do SMC based on ARM SMC Calling Convention.
CONFIG_HAVE_SMCCC is enabled for architectures that may support
the SMC instruction. It's the responsibility of the caller to
know if the SMC instruction is supported by the platform.
