[PATCH] x86: Remove various memory encryption exports

[Christoph Hellwig <hch@lst.de>]

None of these is used in modular code, and we should probably try to
keep it that way.  They can be added back if we really get a legitimate
modular user.

FYI: this was inspired by the fact the s390 copied some of the exports,
which made me wonder why they added them.  I could not find any
potential users either in their patchkit nor in mainline.
