[PATCH v2] cryptodev: add algo enums to string conversion APIs

[Akhil Goyal <gakhil@marvell.com>]

Symmetric/Asymmetric algorithm strings are accessed by application
using arrays in cryptodev lib, which hampers new algorithms addition
in the array due to ABI breakage.
These arrays are now deprecated and will be removed in next ABI break
release.
New APIs are added for getting the algorithm strings based on enum values.
