The CON_ENABLED status of a console is a runtime setting that does not involve the console driver. Drivers must not assume that if the console is disabled then proper hardware management is not needed. For the EFI earlycon case, it is about remapping/unmapping memory for the framebuffer. Use console_is_registered() instead of checking CON_ENABLED.
