- Add usb node;
- Configure pins and clocks;
- Enable USB function in BCSR.
The support was successfully tested using serial and ethernet gadget
drivers.

mpc8272_ads.c is using BCSR bits definitions from pq2ads.h, but
according to User's Guide the bits are wrong for MPC8272ADS boards
(I guess definitions from pq2ads should only be used for PQ2FADS
boards).
So, let's introduce our own definitions for MPC8272ADS, and don't
include pq2ads.h.

Initialize I2C pins on boards with CPM1/CPM2 controllers and document the
i2c bus in booting-without-of.
The boards don't have any I2C chips connected to the I2C bus, so unless
some external chips are connected to the boards, this code is just an
example of setting everything else up.

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.
