BCM270X_DT: Add midi-uart1 overlay

Add a scaler to the ttyS0 clock so that requesting 38400 baud results
in an approximately 31250 baud signal. This is analagous to
midi-uart0, except for ttyS0, which may be useful on Pi3 and also
may avoid an issue with ttyAMA0 failing to synchronise to an active
data stream.
