This series uses the additional DAIs added to the sun8i-codec driver to
add hardware routing for BT SCO (headset) audio on the PinePhone.

The BT audio connection is represented by the "dummy" bt-sco codec. The
connection to the Quectel EG-25G modem via AIF2 works as well, but I do
not include it here because there is no appropriate codec driver in
tree. We have been using an out-of-tree "dummy" codec driver for the
modem similar to bt-sco, and I'm not sure if such a driver would be
desired upstream.

I've applied patches 1-6
