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

[Anoob Joseph]

> 
> 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.
