Of_get_parent and of_find_compatible_node do a of_node_get, and thus a
corresponding of_code_put is needed in both the error case and the normal
return case.
The problem was found using the following semantic match.

1. PCI and reset are factored out into pq2.c. I renamed them from m82xx
to pq2 because they won't work on the Integrated Host Processor line of
82xx chips (i.e. 8240, 8245, and such).
2. The PCI PIC, which is nominally board-specific, is used on multiple
boards, and thus is used into pq2ads-pci-pic.c.
3. The new CPM binding is used.
4. General cleanup.

This is just a rename patch; internal references to mpc82xx_ads will be
changed in the next one.
