[PATCH 2/6] driver core: platform: fix ups for constant struct device_driver

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

Fix up a few places in the platform core code that can easily handle
struct device_driver being constant.  This is part of the work to make
all struct device_driver pointers be constant.
