/* Internal helper to define which fields in the pk_context structure below
* should be used for EC keys: legacy ecp_keypair or the raw (PSA friendly)
* format. It should be noticed that this only affect how data is stored, not
* which functions are used for various operations. The overall picture looks
* like this:
* - if USE_PSA is not defined and ECP_C is then use ecp_keypair data structure
* and legacy functions
* - if USE_PSA is defined and
* - if ECP_C then use ecp_keypair structure, convert data to a PSA friendly
* format and use PSA functions
* - if !ECP_C then use new raw data and PSA functions directly.
*
* The main reason for the "intermediate" (USE_PSA + ECP_C) above is that as long
* as ECP_C is defined mbedtls_pk_ec() gives the user a read/write access to the
* ecp_keypair structure inside the pk_context so he/she can modify it using
* ECP functions which are not under PK module's control.
