add trusted execution environment (tee) driver

TEE working now for Android, tested ok with COPS!

* Updated according to review comments
- Added ST-Ericsson copyright headers to all tee files.
- Fixed problem with not using readl/writel when using ioremap.
- Fixed problem with forgetting to do iounmap on special case.
- Fixed incorrect usage when doing copy_to_user when writing to the device.
- Added architecture dependent file for the tee service that calls the secure world.
- Added support for more several inputs (sharedmemory buffers) for tee.
- Added dummy macro to map MT_MEMORY device.
- Fixed memory leak in secure world due to not closing a TEE session correctly from the kernel.
- Now we only copies input buffer from user space for tee.
- Documented structures in tee.h.
- Moved SVP implementation into arch/arm/mach-ux500 folder.
- Added new config flags for ux500 and SVP regarding TEE driver.
- Update mach-ux500/Kconfig:
  - Enable TEE_UX500 by default when using target hardware.
  - Enabel TEE_SVP by default when building simulator.
- Fix the cache sync problem: not request ROM code to clean cache
- ioremap for ICN_BASE, remove static mapping in cpu-db8500.c.
- Fix ioremap of ICN_BASE and do iounmap after use.
