Stop calling atrtc_set() from the xen timer clock_settime() method. That
removes the only reference to atrtc_set() from outside of atrtc.c, so make it static. The xen timer driver registers as a realtime clock with 1us resolution. In the past that resulted in only the xen timer's clock_settime() getting called, so it would call atrtc_set() to set the hardware clock as well. As of r32090, the clock_settime() method of all registered realtime clocks gets called, so the xen driver no longer needs to chain-call the lower-resolution driver. Thanks to royger@ for talking me through the xen stuff, and for testing.
