Pi 4 doesn't work with Amiga adapters

[tyristori]

Latest 20240213 software. This message is displayed with c0pperdragon's Amiga adapter and with LinuxJedi's CPLD adapter:

CPLD is already flashed on CPLD adapter and works fine with Zero 1.

Doesn't make a difference if single_button_mode is enabled or not.

I've got Pi 4 to work only with the 12-bit adapter.
