Add a new ioctl called TEE_IOC_SHM_REGISTER_FD to register a
shared memory from a dmabuf file descriptor.
This new ioctl will allow the Linux Kernel to register a buffer
to be used by the Secure Data Path OPTEE OS feature.

Please find more information here:
https://static.linaro.org/connect/san19/presentations/san19-107.pdf

Patch tested on Hikey 6220.
