Staging: sep: Introduce sep driver 



This driver is for the Security Processor, a dedicated encryption
and decryption driver that is used on the Intel mobile platform.

This has been checked with checkpatch and there are four
warnings for lines over 80 charactors.

There is one compile warning. This is for a function that is
only used if the rar register driver is needed. There is an
ifdef in a header file that stubs out the rar register driver
if the rar register is not configured.

This driver does add a configuration, which is CONFIG_DX_SEP.

Todo's so far (from Alan Cox)

- Fix firmware loading - Done 09/10 M. Allyn

- Get firmware into firmware git tree - Firmware is non open source

- Review and tidy each algorithm function - Done 09/10 M. Allyn

- Check whether it can be plugged into any of the kernel crypto API

  interfaces - Crypto API 'glue' is still not ready to submit

- Do something about the magic shared memory interface and replace it

  with something saner (in Linux terms) - Done 09/10 M. Allyn

- Clean up unused ioctls - Needs vendor help

- Clean up unused fields in ioctl structures - Needs vendor help

- 64 bit size to be used for all user space addresses passed

  to ioctl - Done 10/10 M. Allyn
