ASoC: tpa6130a2: Revisit power-up sequence

There are no known problems with current power-up sequence which first sets
the /shutdown pin high and then enables the supply. However, swap the order
so that the device is kept in shutdown/reset mode during the supply voltage
transition since slowly rising voltages can usually cause problems if the
device is not kept in reset.
