s390x: avoid to set serial console

[alicefr]

The serial console and the sclpconsole conflict with this error on s390x: qemu-system-s390x: -device sclpconsole,chardev=console: Multiple VT220 operator consoles are not supported qemu-system-s390x: -device sclpconsole,chardev=console: SCLP event initialization failed.

We can only enable the sclpconsole console

LGTM. @amluto do you have a better idea to solve this issue?

[amluto]

I clearly don't understand what's going on here. Without this patch, we get this:

-device sclpconsole,chardev=console
-parallel none
-net none
-echr 1
-serial none
-chardev stdio,id=console,signal=off,mux=on
-serial chardev:console
-mon chardev=console

This does indeed fail, but removing -serial none doesn't help.

Want to make a new patch that wires this up in a somewhat sensible way through architectures.py and makes the correct change to the arguments? It looks like there should be a default function that supplies -serial chardev:console and an s390x override that supplies the -device sclpconsole,chardev=console.

I tested the solution proposed in #75, and since it's more generic I believe that we can have it merged. What do you think?
