The only minor comment I have on this is... the formatting of the
above. Wouldn't:

if (priv->hw_version >= MVPP22 &&
mvpp2_read(priv, MVPP2_VER_ID_REG) == MVPP2_VER_PP23)
priv->hw_version = MVPP23;

read better?

Do we need to even check priv->hw_version here? Isn't this register
implemented in PPv2.1 where it contains the value zero?
