Clean up some remnants of TLS pre-1.2 support
Now that support for earlier version have been removed, we no longer need to care about them. Since TLS 1.3 is being gradually introduced, we might still need a version check in some places - but here the function is called ssl_tls12_populate_tranform() and TLS 1.3 has its own function mbedtls_ssl_tls13_populate_transform(), so when this function is called we just know we're using TLS 1.2. Reviewer hint: use the -b option of git diff / git show Signed-off-by: Manuel Pégourié-Gonnard <manuel.pegourie-gonnard@arm.com>
