0c2cfc767d driver/tee: add optee client driver module
The driver's main purpose is to support the porting of the open source
component optee_client (https://github.com/OP-TEE/optee_client) to nttux.

The basic function of the driver module is to convert the REE application layer data and send it to the TEE through rpmsg.

The main functions include
1 driver registration.
we need to register a device driver(/dev/tee0) through optee_register function.
2 open the driver
3 ioctl the driver
The ioctl command passes different parameters and commands, and interacts with the TEE through rpmsg.
4 close the driver
