In amdgpu_atif_handler, when hotplug event received, remove
ATPX_DGPU_REQ_POWER_FOR_DISPLAYS check. This bit's check will cause missing
system resume.

kfree(NULL) is safe, so removes NULL check before freeing the mem.
This patch also fix the ifnullfree.cocci warnings.

ACPI ATIF has a function called query
backlight transfer characteristics. Among the
information returned by this function is
the minimum and maximum input signals for the
backlight
Call that function on ACPI init. When DM
backlight device is updated, copy over the
backlight caps into DM, but only once. Use
the backlight caps in the backlight-to-dc
calculation

The ACPI interface in AMD was a few years out of date
and contained some unused and deprecated functions
Remove functions: Select Active Displays, Get Lid State,
Get TV Standard, Set TV Standard, Get Panel Expansion Mode,
Set Panel Expansion Mode, Get Graphics Device Types
Add functions: Query Backlight Transfer Characteristics,
Ready To Undock Notification
Changed functions: Get System Parameters,
Get System BIOS Requests
All changes are right from the standard
ATI ACPI Control Methods V0.44

Currently we return NOTIFY_DONE for any event which we don't think is
ours. However, many laptops will send more then just an ATIF event and
will also send an ACPI_VIDEO_NOTIFY_PROBE event as well. Since we don't
check for this, we return NOTIFY_DONE which causes a keypress for the
ACPI event to be propogated to userspace. This is the equivalent of
someone pressing the display key on a laptop every time there's a
hotplug event.
So, check for ACPI_VIDEO_NOTIFY_PROBE events and suppress keypresses
from them.

The other day I was testing one of the HP laptops at my office with an
i915/amdgpu hybrid setup and noticed that hotplugging was non-functional
on almost all of the display outputs. I eventually discovered that all
of the external outputs were connected to the amdgpu device instead of
i915, and that the hotplugs weren't being detected so long as the GPU
was in runtime suspend. After some talking with folks at AMD, I learned
that amdgpu is actually supposed to support hotplug detection in runtime
suspend so long as the OEM has implemented it properly in the firmware.
On this HP ZBook 15 G4 (the machine in question), amdgpu wasn't managing
to find the ATIF handle at all despite the fact that I could see acpi
events being sent in response to any hotplugging. After going through
dumps of the firmware, I discovered that this machine did in fact
support ATIF, but that it's ATIF method lived in an entirely different
namespace than this device's handle (the device handle was
\_SB_.PCI0.PEG0.PEGP, but ATIF lives in ATPX's handle at
\_SB_.PCI0.GFX0).
So, fix this by probing ATPX's ACPI parent's namespace if we can't find
ATIF elsewhere, along with storing a pointer to the proper handle to use
for ATIF and using that instead of the device's handle.
This fixes HPD detection while in runtime suspend for this ZBook!
v2: Update the comment to reflect how the namespaces are arranged
based on the system configuration. (Alex)

Currently, there is nothing in amdgpu that actually uses these structs
other than amdgpu_acpi.c. Additionally, since we're about to start
saving the correct ACPI handle to use for calling ATIF in this struct
this saves us from having to handle making sure that the acpi_handle
(and by proxy, the type definition for acpi_handle and all of the other
acpi headers) doesn't need to be included within the amdgpu_drv struct
itself. This follows the example set by amdgpu_atpx_handler.c.

it is required if a platform supports PCIe root complex
core voltage reduction. After receiving this notification,
SBIOS can apply default PCIe root complex power policy.

This is a left over from radeon, amdgpu doesn't support any
non-atombios parts and amdgpu_device_init would bail if the
check for atombios failed anyway.

This was added to two radeon files even though they don't use any
vga_switcheroo symbols, the amdgpu fork inherited them:
Added to amdgpu_acpi.c by commit d7a2952f1ade ("drm/radeon: Add
support for the ATIF ACPI method to the radeon driver").
Added to amdgpu_bios.c by commit 6a9ee8af344e ("vga_switcheroo:
