s390-ccw: parse and set boot menu options
Set boot menu options for an s390 guest and store them in
the iplb. These options are set via the QEMU command line
option:
-boot menu=on|off[,splash-time=X]
or via the libvirt domain xml:
<os>
<bootmenu enable='yes|no' timeout='X'/>
</os>
Where X represents some positive integer representing
milliseconds.
Any value set for loadparm will override all boot menu options.
If loadparm=PROMPT, then the menu will be enabled without a
timeout.
