Staging: remove heci driver

Intel has officially abandoned this project and does not want to
maintian it or have it included in the main kernel tree, as no one
should use the code, it's not needed anymore.

tristate "Intel Management Engine Interface (MEI) Support"
depends on PCI
---help---
The Intel Management Engine Interface (Intel MEI) driver allows
applications to access the Active Management Technology
firmware and other Management Engine sub-systems.

TODO:
- fix user/kernel pointer mess in the ioctl handlers as pointed
out by sparse.
- resolve the ioctls and see if most of them can just be simple
sysfs files
- fix locking issues that sparse points out at the least.
