Dom0less is Xen mode without privileged domain. All guests are created according to hypervisor device tree configuration on boot. Thus, there is no Dom0 with console daemon, that usually manages console output from domains. Zephyr OS contains 2 serial drivers related to Xen hypervisor: regular with console shared page and consoleio-based. The first one is for setups with console daemon and usually was used for Zephyr DomU guests. The second one previously was used only for Zephyr Dom0 and had corresponding Kconfig options. But consoleio is also used as interface for DomU output on Dom0less setups and should be configurable without XEN_DOM0 option. Add corresponding XEN_DOM0LESS config to Xen Kconfig files and proper dependencies in serial drivers.
