In comparison, the aead driver puts the hardware driver name as a suffix,
not a prefix, and uses dashes rather than underscores and parenthesis:
> +			.cra_name = "gcm(aes)",
> +			.cra_driver_name = "gcm-aes-ycc",

and the pk driver uses a prefix with a dash:

Although the existing drivers are wildly inconsistent, it would be nice
if this driver was at least consistent with itself. Suffixes with dashes
seem to be the most popular, so consider these formats:
  cbc-aes-ycc
  gcm-aes-ycc
  rsa-ycc
