In the quest to make struct device constant, start by making to_auziliary_drv() return a constant pointer so that drivers that call this can be fixed up before the driver core changes.

As the return type previously was not constant, also fix up all callers that were assuming that the pointer was not going to be a constant one in order to not break the build.
