Changes to Config.txt for Pi Zero 2W Ubuntu

config.txt

# The unusual ordering below is deliberate; older firmwares (in particular the
# version initially shipped with bionic) don't understand the conditional
# [sections] below and simply ignore them. The Pi4 doesn't boot at all with
# firmwares this old so it's safe to place at the top. Of the Pi2 and Pi3, the
# Pi3 uboot happens to work happily on the Pi2, so it needs to go at the bottom
# to support old firmwares.

# The following settings are "defaults" expected to be overridden by the
# included configuration. The only reason they are included is, again, to
# support old firmwares which don't understand the "include" command.
