DRM: armada: fix corruption while loading cursors

Loading cursors to the LCD controller's SRAM can be corrupted when the
configured pixel clock is relatively slow.  This seems to be caused
when we write back-to-back to the SRAM registers.

There doesn't appear to be any status register we can read to check
when an access has completed.

Inserting a dummy read between the writes appears to fix the problem.

drm/i915: move power domain init earlier during system resume

During resume the intel hda audio driver depends on the i915 driver
reinitializing the audio power domain. Since the order of calling the
i915 resume handler wrt. that of the audio driver is not guaranteed,
move the power domain reinitialization step to the resume_early
handler. This is guaranteed to run before the resume handler of any
other driver.

The power domain initialization in turn requires us to enable the i915
pci device first, so move that part earlier too.

Accordingly disabling of the i915 pci device should happen after the
audio suspend handler ran. So move the disabling later from the i915
resume handler to the resume_late handler.

v2:
- move intel_uncore_sanitize/early_sanitize earlier too, so they don't
  get reordered wrt. intel_power_domains_init_hw()

    drm/i915: disable rings before HW status page setup

we reordered stopping the rings to do so before we set the HWS register.
However, there is an extra workaround for g45 to reset the rings twice,
and for consistency we should apply that workaround before setting the
HWS to be sure that the rings are truly stopped.

Here's the latest iteration of the universal planes work, which I believe is
finally ready for merging.  Aside from the minor driver patches to use the
new drm_for_each_legacy_plane() macro for plane loops, these should all have
an r-b from Rob Clark now.

Actual userspace-visibility is currently hidden behind a
drm.universal_planes module parameter so that we can do some experimental
testing of this before flipping it on universally.

drm/crtc-helper: don't disable disconnected outputs

    drm/i915: don't disable disconnected outputs

This was originally introduced to make encoder sharing on radone
easier for userspace, but:

- It is policy and as such belongs into userspace. E.g. personally I'm
  fairly annoyed that a flaky cable results in permanent changes of
  the desktop layout, so I'll kick out DEs which do this. Worse if the
  kernel also tries to be clever.

- It's inconsistent: We only kill disconnected outputs on setCrtc
  (which userspace might also call when just changing the
  framebuffer), but not when e.g. we receive a hpd event or in the
  output poll worker.

- It's unexpected behaviour for the userspace driver, at least in the
  intel ddx we've had tons of bugs where the driver fell over and
  killed the X session becuase pageflips/vblanks suddenly stopped
  working. We've had to fix this by wrapping every single setCrtc int
  a big "recover kms state from the kernel again" operation.

- It's suprising for the kernel, too: It took a few mails between Rob,
  Matt and me for them to notice that little dragon wreaking havoc
  with the universal plane framebuffer refcounting.

- Userspace can cope with it and e.g. Gnome already kills disconnected
  outputs and reconfigures the desktop automatically. And since there
  have been no regression reports for the i915 change from over 1 year
  ago I think all other DEs are also ready.

Note that the lines removed in this patch go back to

drm: Specify a bit more the DRM_CAP_CURSOR_{WIDTH, HEIGHT} caps

capabilities, to the point I think it's better to document the intention
and API contract.

The comment documents the current situation:
 - the radeon driver returns the only valid size for the hw
 - i915 returns the maximun cursor size
 - other drivers fall back to returning 64x64

The common contract is to return a valid cursor size.
