alloc_workqueue replaces deprecated create_singlethread_workqueue().

Each hardware CRTC has a single flip work queue.
When a radeon_flip_work_func item is queued, it needs to be executed
ASAP because even a slight delay may cause the flip to be delayed by
one refresh cycle.

Hence, a dedicated workqueue with WQ_HIGHPRI set, has been used here
since a delay can cause the outcome to miss the refresh cycle.

Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary here.

Just about all of amdgpu's connector probing functions try to acquire
runtime PM refs. If we try to do this in the context of
amdgpu_resume_kms by calling drm_helper_hpd_irq_event(), we end up
deadlocking the system.

Since we're guaranteed to be holding the spinlock for RPM in
amdgpu_resume_kms, and we already know the GPU is in working order, we
need to prevent the RPM helpers from trying to run during the initial
connector reprobe on resume.

There's a couple of solutions I've explored for fixing this, but this
one by far seems to be the simplest and most reliable (plus I'm pretty
sure that's what disable_depth is there for anyway).

Reproduction recipe:
  - Get any laptop dual GPUs using PRIME
  - Make sure runtime PM is enabled for amdgpu
  - Boot the machine
  - If the machine managed to boot without hanging, switch out of X to
    another VT. This should definitely cause X to hang infinitely.

Changes since v1:
  - add appropriate #ifdef checks for CONFIG_PM. This is not very
    useful, but it appears some kernel test suites test compiling amdgpu
    with CONFIG_PM disabled, which results in this patch breaking the builds
    if we don't include this #ifdef
