Subject: [PATCH 1/6] auxbus: make to_auxiliary_drv accept and return a constant pointer
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.
