Fixup: Impl. MBEDTLS_PK_ECKEY, not MBEDTLS_PK_ECDSA, via TinyCrypt

The PK-type MBEDTLS_PK_ECDSA isn't really used by the library.
Especially, when parsing a generic EC key, a PK context of type
MBEDTLS_PK_ECKEY will be requested. Hence, to drop in TinyCrypt
for the legacy-ECC implementation, the PK type that TinyCrypt
implements must be MBEDTLS_PK_ECKEY.
