[PATCH 04/40] cryptodev: reduce number of comments in asym xform

[Arek Kusztal <arkadiuszx.kusztal@intel.com>]

- Reduced number of comments in asymmetric xform.
Information describing basic functionality of well known
algorithms are unnecessary.
- Added information about data memory lifetime.
It was specified how user should work with private data,
and it is user's responsability to clear it.
- Removed NONE asymetric xform.
