Based on linux-gpio discussion [1], it is best practice to make the
gpio-line-names unique. Generic names like "[ethernet]" are replaced
with the name of the unique signal on the AM3358 SoC ball corresponding
to the gpio line. "[NC]" is also renamed to the standard "NC" name to
represent "not connected".
