[v5,0/5] drm: Move struct drm_device.pdev to legacy

Message

For v5, I moved the non-assignment of pdev in i915 into a separate
patch as suggested by Chris. Hopefully, this will help with merging the
patches into the rsp i915 trees. The core and vmwgfx changes have been
merged into drm-tip already.

The pdev field in struct drm_device points to a PCI device structure and
goes back to UMS-only days when all DRM drivers were for PCI devices.
Meanwhile we also support USB, SPI and platform devices. Each of those
uses the generic device stored in struct drm_device.dev.

To reduce duplication and remove the special case of PCI, this patchset
converts all modesetting drivers from pdev to dev and makes pdev a field
for legacy UMS drivers.

For PCI devices, the pointer in struct drm_device.dev can be upcasted to
struct pci_device; or tested for PCI with dev_is_pci(). In several places
the code can use the dev field directly.

After converting all drivers and the DRM core, the pdev fields becomes
only relevant for legacy drivers. In a later patchset, we may want to
convert these as well and remove pdev entirely.

v5:
	* remove assignment in later patch (Chris)
v4:
	* merged several patches
	* moved core changes into separate patch
	* vmwgfx build fix
v3:
	* merged several patches
	* fix one pdev reference in nouveau (Jeremy)
	* rebases
v2:
	* move whitespace fixes into separate patches (Alex, Sam)
	* move i915 gt/ and gvt/ changes into separate patches (Joonas)
