mb/google/{auron,link,slippy}/acpi: Drop EC serial port
The EC serial port on these devices is not accessible to the end user and exposing it to the OS via ACPI serves no purpose. Debugging over the EC serial port (via the servo interface) does not require the ACPI exist. Drop it since it's not needed and serves no purpose. TEST=build/boot Win11 on auron/link/slippy, verify Windows Device Manager no longer shows an unusable COM port.
