Enable userspace to allocate shared memory with QTEE. Since
QTEE handles shared memory as object, a wrapper is implemented
to represent tee_shm as an object. The shared memory identifier,
obtained through TEE_IOC_SHM_ALLOC, is transferred to the driver using
TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF_INPUT/OUTPUT.
