Done in v3:

https://lore.kernel.org/linux-rockchip/86fcf349-0a7a-4618-9001-612371b0f71b@symple.nz/

Re-tested on the LG G3 OLED (the original reporting sink) at
148.5 / 185.625 / 297 / 594 MHz; audio plays at all four.  v3
also drops ~200 lines of open-coded N/CTS tables and search
functions that the helper makes redundant.
