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.

Please use types with explicit endianness, e.g. __le32. I'm assuming TZ will always be little-endian, regardless of the host OS
