serial: core: Add serial_base_match_and_update_preferred_console()
Let's add serial_base_match_and_update_preferred_console() for consoles
using DEVNAME:0.0 style naming.
The earlier approach to add it caused issues in the kernel command line
ordering as we were calling __add_preferred_console() again for the
deferred consoles.
