parisc: Add opt/hostid fw_cfg option to change hostid

Allow the user to select another default hostid value.
In HP/UX the "uname -i" command show the number,
and in Linux it's visible in the /proc/cpuinfo output.

The default hostid number is 2006243326, any other integer value can
be selected with this qemu option:
    -fw_cfg opt/hostid,string=334455
