The Versal Net variant comes with a dedicated PKI engine. This driver
makes use of the engine for ECDSA P-256, P-384, and P-521 sign, verify
and key generation operations.

Split NVM code into two seperate drivers, one for Versal, one for Versal
Net, since both variants have very different NVM PLM code.
