Profiling the suspend and resume time [1] on a MSI B350M MORTAR (MS-7A37) with
AMD Ryzen 3 2200G with Radeon Vega Graphics with Linux 4.18-rc6+ and
amd-staging-drm-next [2], `pci_pm_suspend()` takes over one second, which is
too long [3], cf. <a class="bz_bug_link
bz_status_NEW "

href="show_bug.cgi?id=107278">bug 107278</a> [3].
This is spent in `amdgpu_device_ip_resume_phase2()`, where 505 ms are spent in
`flush_delayed_work()`.
