x86: earlyprintk: Fix regression to handle serial,ttySn as 1 arg
Commit c953094 ("early_printk: Allow more than one early console") introduced a regression in the parsing of the earlyprintk= kernel arguments. If you specify "earlyprintk=serial,ttyS0,115200" as a kernel argument, the "serial,ttyS" should be parsed as a single argument and not as "serial" and then "ttyS". Also update the documentation to reflect you can specify the ttyS directly without the "serial" argument.
