This series fixes minor sort-order issues in the Amlogic bindings yaml and
dtb Makefile, then converts the existing ODROID-C2 dts into dtsi so we can
support its new sister product the ODROID-HC4.

I've also given the devices different audio card names. This is partly
cosmetic, but also because HC4 is HDMI-only while C4 can be used with
other i2c audio devices via an expansion connector so users may want to
use different alsa configs.

Patches to support the spifc chip are still being upstreamed [0] so this
will be addressed in a follow up. A WIP patch for the dts change can be
found in my amlogic-5.11.y dev branch [1].

For reference, here's dmesg from LibreELEC on 5.11-rc5 [2].

^ should be 16MB, I forgot to amend. I can send a v2 series if needed.

HC4:~ # dmesg | grep spi
