Subject: [PATCH] azure: ensure early boot messages are directed to the serial
 console

In the event that there's an issue with early boot, setting
earlyprintk=ttyS0 ensures that the messages are routed to the serial
console so it can be debugged.

This particular option is documented as required in the Azure VM
certification FAQ[0].
