PM / Runtime: Update last_busy in rpm_resume
commit 56f487c78015936097474fd89b2ccb229d500d0f upstream.
If we don't update last_busy in rpm_resume, devices can go back
to sleep immediately after resume. This happens at least in
cases where the device has been powered off and does not have
any interrupt pending until there's something in the FIFO.
