  Makes creation of shm pools more flexible by adding new more primitive
  functions to allocate a shm pool. This makes it easier to add driver
  specific shm pool management.

  Initial patch for generic TEE subsystem.
  This subsystem provides:
  * Registration/un-registration of TEE drivers.
  * Shared memory between normal world and secure world.
  * Ioctl interface for interaction with user space.
  * Sysfs implementation_id of TEE driver

  A TEE (Trusted Execution Environment) driver is a driver that interfaces
  with a trusted OS running in some secure environment, for example,
  TrustZone on ARM cpus, or a separate secure co-processor etc.

  The TEE subsystem can serve a TEE driver for a Global Platform compliant
  TEE, but it's not limited to only Global Platform TEEs.

  This patch builds on other similar implementations trying to solve
  the same problem:
  * "optee_linuxdriver" by among others
  Jean-michel DELORME and
  Emmanuel MICHEL
  * "Generic TrustZone Driver" by Javier González
