Those components were introduced in #7103, resolving #6622: Some PSA
ECC size macros are too small when the largest accelerated curve is
larger than the largest built-in curve.
At that point, it was not possible yet to omit all built-in curves,
so we made these components that had only one (small) curve built-in and
all the others accelerated.
Now that it's possible to disable all ECC built-ins, and we have tests
doing that, we don't need that kind of fiddling any more.
Note: these component disabled RSA in order to make sure max key size
macros were not taken from RSA. We have test components with all of ECC
accelerated and RSA disabled
(component_test_psa_crypto_config_accel_ecc_no_bignum and
component_test_psa_crypto_config_accel_ecc_ffdh_no_bignum), making the
"all curves except one" components really redundant.
Note: removing them was one of the items in #7757.
