Subject: doc, xen: Mention 'earlyprintk=xen' in the documentation.

From: Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>

commit 2482a92e7d17187301d7313cfe5021b13393a0b4 upstream.

The earlyprintk for Xen PV guests utilizes a simple hypercall
(console_io) to provide output to Xen emergency console.

Note that the Xen hypervisor should be booted with 'loglevel=all'
to output said information.
