23a1a9e54e drm/amdgpu: Disable RPM helpers while reprobing connectors on resume
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

b636a1b3d6 drm/amdgpu: Poll for both connect/disconnect on analog connectors
DRM_CONNECTOR_POLL_CONNECT only enables polling for connections, not
disconnections. Because of this, we end up losing hotplug polling for
analog connectors once they get connected.

Easy way to reproduce:
 - Grab a machine with an AMD GPU and a VGA port
 - Plug a monitor into the VGA port, wait for it to update the connector
   from disconnected to connected
 - Disconnect the monitor on VGA, a hotplug event is never sent for the
   removal of the connector.

Originally, only using DRM_CONNECTOR_POLL_CONNECT might have been a good
idea since doing VGA polling can sometimes result in having to mess with
the DAC voltages to figure out whether or not there's actually something
there since VGA doesn't have HPD. Doing this would have the potential of
showing visible artifacts on the screen every time we ran a poll while a
VGA display was connected. Luckily, amdgpu_vga_detect() only resorts to
this sort of polling if the poll is forced, and DRM's polling helper
doesn't force it's polls.

Additionally, this removes some assignments to connector->polled that
weren't actually doing anything.
