A few display and GPUVM fixes for 4.18.

A few more fixes for 4.18. Two display fixes and a fix to avoid a segfault if
the GPU does not power up properly on resume.  These are on top of my pull
from earlier this week.

Rather than using the index variable stored in vram.  If
the device fails to come back online after a resume cycle,
reads from vram will return all 1s which will cause a
segfault. Based on a patch from Thomas Martitz <kugel@rockbox.org>.
This avoids the segfault, but we still need to sort out
why the GPU does not come back online after a resume.

[Why]
When a dce100 asic was suspended, the clocks were not set to 0.
Upon resume, the new clock was compared to the existing clock,
they were found to be the same, and so the clock was not set.
This resulted in a pernicious blackscreen.

[How]
In atomic commit, check to see if there are any active pipes.
If no, set clocks to 0

The driver is expecting clock frequency in kHz, while SMU returns
the values in 10kHz, which causes the bandwidth validation to fail

4.18 has the faulty clock assignment in pp_to_dc_clock_levels_with_latency
only, which is only used by Vega. Make sure we multiply these values
by 10 here, as we do for other ASICs as powerplay assigned them
wrong. 4.19 has the proper fix in powerplay.

Problem: When PD/PT update made by CPU root PD was not yet mapped causing
page fault.

Fix: Verify root PD is mapped into CPU address space.

v2:
Make sure that we add the root PD to the relocated list
since then it's get mapped into CPU address space bt default
in amdgpu_vm_update_directories.

v3:
Drop change to not move kernel type BOs to evicted list.

v4:
Remove redundant bo move to relocated list.

This breaks DDC in certain cases.  Revert for 4.18 and previous kernels.
For 4.19, this is fixed with the following more extensive patches:

drm/amd/display: Break out function to simply read aux reply
drm/amd/display: Return aux replies directly to DRM
drm/amd/display: Right shift AUX reply value sooner than later

Use new return type vm_fault_t for fault handler. For now,
this is just documenting that the function returns a
VM_FAULT value rather than an errno. Once all instances are
converted, vm_fault_t will become a distinct type.

Ref-> commit 1c8f4220 ("mm: change return type to
vm_fault_t") was added in 4.17-rc1 to introduce the new
typedef vm_fault_t. Currently we are making change to all
drivers to return vm_fault_t for page fault handlers. As
part of that char/agp driver is also getting changed to
return vm_fault_t type from fault handler.

Just like with PIPESTAT, the edge triggered IIR on i965/g4x
also causes problems for hotplug interrupts. To make sure
we don't get the IIR port interrupt bit stuck low with the
ISR bit high we must force an edge in ISR. Unfortunately
we can't borrow the PIPESTAT trick and toggle the enable
bits in PORT_HOTPLUG_EN as that act itself generates hotplug
interrupts. Instead we just have to loop until we've cleared
PORT_HOTPLUG_STAT, or we just give up and WARN.

v2: Don't frob with PORT_HOTPLUG_EN

Host1x's CDMA can't access the command buffers if IOMMU and Host1x
firewall are enabled in the kernels config because firewall doesn't map
the copied buffer into IOVA space. Fix this by skipping IOMMU
initialization if firewall is enabled as firewall merges sparse cmdbufs
into a single contiguous buffer and hence IOMMU isn't needed in this case.

Pull scheduler fixes from Thomas Gleixner:

 - The hopefully final fix for the reported race problems in
   kthread_parkme(). The previous attempt still left a hole and was
   partially wrong.

 - Plug a race in the remote tick mechanism which triggers a warning
   about updates not being done correctly. That's a false positive if
   the race condition is hit as the remote CPU is idle. Plug it by
   checking the condition again when holding run queue lock.

 - Fix a bug in the utilization estimation of a run queue which causes
   the estimation to be 0 when a run queue is throttled.

 - Advance the global expiration of the period timer when the timer is
   restarted after a idle period. Otherwise the expiry time is stale and
   the timer fires prematurely.

 - Cure the drift between the bandwidth timer and the runqueue
   accounting, which leads to bogus throttling of runqueues

 - Place the call to cpufreq_update_util() correctly so the function
   will observe the correct number of running RT tasks and not a stale
   one.
