Fix SHA256 usage on older CESA versions

Summary

Adding SHA256 support to Marvell crypto driver resulted in regression
for older SoC's, not capable of handling this mode in hardware.

imho, this is papering over problem in DTS. If CESA device have more variants, then each one must have different 'compatible' string.
In other words, you cannot use same 'compatible' string for different devices (if the difference cannot be determined at runtime).

BTW, why you can't use 'standard' DTS for Marvell SOCs, even with FBSD specific overlay?

Ok, will add compatible-based revision differentiation instead of the ifdefs.

Updated version contains implemented SOC-ID based hardware differentiation.
