[PATCH] hw/i386/pc: Add a description for the i8042 property

[Kamil Szczęk]

While working on exposing the i8042 property in libvirt I noticed that
the property is missing a description. This adds a simple description
so that QEMU users don't have to dig in the source code to figure out
what this option does.
