drm/nouveau/disp/mcp7x: disable dptmds workaround
The workaround appears to cause regressions on these boards, and from inspection of RM traces, NVIDIA don't appear to do it on them either. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Tested-by: Roy Spliet <nouveau@spliet.org>

CPUs are online before RAPL is initialized. A possible fix would be to reintroduce the mess which allocates a package data structure in CPU prepare and when it turns out to already exist in starting throw it away later in the CPU online callback. But that's a horrible hack and not required at all because RAPL becomes functional for perf only in the CPU online callback. That's correct because user space is not yet informed about the CPU being onlined, so nothing caan rely on RAPL being available on that particular CPU. Move the allocation to the CPU online callback and simplify the hotplug handling. At this point the package mapping is established and correct. This also adds a missing check for available package data in the event_init() function.
