parisc: Prevent hung tasks when printing inventory on serial console
commit c8708d758e715c3824a73bf0cda97292b52be44d upstream.
Printing the inventory on a serial console can be quite slow and thus may
trigger the hung task detector (CONFIG_DETECT_HUNG_TASK=y) and possibly
reboot the machine. Adding a cond_resched() prevents this.
