Arnd Bergmann 25b67f373b TEE shared memory cleanup for v5.18
- The TEE shared memory pool based on two pools is replaced with a single
   somewhat more capable pool.
 - Replaces tee_shm_alloc() and tee_shm_register() with new functions
   easier to use and maintain.  The TEE subsystem and the TEE drivers are
   updated to use the new functions instead.
 - The TEE based Trusted keys routines are updated to use the new
   simplified functions above.
 - The OP-TEE based rng driver is updated to use the new simplified
   functions above.
 - The TEE_SHM-flags are refactored to better match their usage
