parisc: Add opt/hostid fw_cfg option to change hostid
Allow the user to select another hostid value.
In HP/UX the "uname -i" command shows the number,
and in Linux it's visible in the /proc/cpuinfo output.
The default hostid number is 2006243326, any other value can
be selected with this qemu command line option:
-fw_cfg opt/hostid,string=334455
