[PATCH] Export device_add_attributes() so drivers can use it.

[Grant Likely <grant.likely@secretlab.ca>]

From: Grant Likely <grant.likely@secretlab.ca>

I find myself using the pattern of device_add_attributes() and
device_remove_attributes() frequently in my drivers.  Rather than
reinventing the wheel every time, I'm floating this patch to export
the symbols to see how it is received.  If this looks okay then I'll
rework my drivers and post additional patches to use these functions.
