Drivers (both built-in and external) need to declare their context structures in a way such that they are accessible by the to-be-autogenerated crypto_driver_contexts.h file. That file lives in include/psa, which means all builtin driver context structure declarations also need to live in include/psa. Signed-off-by: Steven Cooreman <steven.cooreman@silabs.com>
