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.
