'co'dec < 'cp'u, please reshuffle

and leave a \n between the property (link-name) and the following subnode
as well as between the individual subnodes (but not after the last one)

Because they have identical properties, you can squash GPIOs 2-4 into
'lpass_qua_mi2s_data' with:

gpios = "gpio2", "gpio3", "gpio4";
