ASoC: meson: add reset binding
The g12a audio subsystem, which is a derivative of the axg subsystem, provides a dedicated reset line for each of the audio components. The axg did not provide that and it is unclear if/when these reset are required. The reset already helped solve a channel mapping issue on the tdm formatter devices. Let's add the reset binding for the other components, so we can describe this in DT. We'll use it later on in the driver when/if needed.
