You are correct, but I was thinking that I should make the codec bits optional
in the event someone had a RK817 and didn't want to use the codec. If you think
this or the rest of the bits should not be optional please let me know. I still
think it's best that at least the cell be optional so users can build a kernel
without the audio if they so choose (I tested both building this module and
audio codec with no devicetree entry - you get a dmesg log error but nothing
else, and building with the devicetree entry but no driver - nothing happens).

If we enable the regmap bits unconditionally, is there any potential harm?

Thank you.
