Set default pin used for 'Serial' instance (ex: ST-Link)
When Serialx instanciation, check if it is the generic 'Serial' then set Rx/Tx pins if defined else get the pins of the first peripheral occurence in PinMap Anyway, Rx/Tx pins could be changed later using Serialx.setRx/setTx methods before call the Serialx.begin() Signed-off-by: Frederic.Pillon <frederic.pillon@st.com>
