Subject: [PATCH] earlycon: 8250: Fix command line regression

Restore undocumented behavior of kernel command line parameters of
the forms:
    console=uart[8250],io|mmio|mmio32,<addr>[,options]
    console=uart[8250],<addr>[,options]
where 'options' have not been specified; in this case, the hardware
is assumed to be initialized.

Fixes: c7cef0a84912cab3c9df8 ("console: Add extensible console matching")
