driver core: fix up some missing class.devnode() conversions. 



In commit ff62b8e6 ("driver core: make struct class.devnode() take a
const *") the ->devnode callback changed the pointer to be const, but a
few instances of PowerPC drivers were not caught for some reason.

Fix this up by changing the pointers to be const.
