Bail from the pci_driver probe function instead of from the drm_driver
load function.

This avoid /dev/dri/card0 temporarily getting registered and then
unregistered again, sending unwanted add / remove udev events to
userspace.

Specifically this avoids triggering the (userspace) bug fixed by this
plymouth merge-request:
https://gitlab.freedesktop.org/plymouth/plymouth/merge_requests/59

Note that despite that being a userspace bug, not sending unnecessary
udev events is a good idea in general.

An earlier patch of mine disabled some #warning statements
that get in the way of build testing, but then another
instance was added around the same time.

Remove that as well.

When CONFIG_PERF_EVENTS is disabled, we cannot compile the pmu
portion of the amdgpu driver:

drivers/gpu/drm/amd/amdgpu/amdgpu_pmu.c:48:38: error: no member named 'hw' in 'struct perf_event'
        struct hw_perf_event *hwc = &event->hw;
                                     ~~~~~  ^
drivers/gpu/drm/amd/amdgpu/amdgpu_pmu.c:51:13: error: no member named 'attr' in 'struct perf_event'
        if (event->attr.type != event->pmu->type)
            ~~~~~  ^
...

The same bug was already fixed by commit d155bef0636e ("amdgpu: make pmu
support optional") but broken again by what looks like an incorrectly
rebased patch.

In acp_hw_init there are some allocations that needs to be released in
case of failure:

1- adev->acp.acp_genpd should be released if any allocation attemp for
adev->acp.acp_cell, adev->acp.acp_res or i2s_pdata fails.
2- all of those allocations should be released if
mfd_add_hotplug_devices or pm_genpd_add_device fail.
3- Release is needed in case of time out values expire.

We reset the GPU as part of our hibernation sequence so we need
to make sure we don't mark vram as lost in that case.

Pull drm fixes from Dave Airlie:
 "Fixes built up over the past 1.5 weeks or so, it's two weeks of
  amdgpu, some core cleanups and some panfrost fixes. I also finally
  figured out why my desktop was slow to do a bunch of stuff (someone
  gave it an IPv6 address which can't reach anything!).

  core:
   - Some cleanups and fixes in the self-refresh helpers
   - Some cleanups and fixes in the atomic helpers

  amdgpu:
   - Fix a 64 bit divide
   - Prevent a memory leak in a failure case in dc
   - Load proper gfx firmware on navi14 variants
   - Add more navi12 and navi14 PCI ids
   - Misc fixes for renoir
   - Fix bandwidth issues with multiple displays on vega20
   - Support for Dali
   - Fix a possible oops with KFD on hawaii
   - Fix for backlight level after resume on some APUs
   - Other misc fixes

  panfrost:
   - Multiple panfrost fixes for regulator support and page fault
     handling"
