Only really pci devices have a business setting this - it's for
figuring out whether the legacy vga stuff should be nuked too. And
with the preceding two patches those are all using the pci version of
this.
Which means for all other callers primary == false and we can remove
it now.
v2:
- Reorder to avoid compile fail (Thomas)
- Include gma500, which retained it's called to the non-pci version.
v4:
- fix Daniel's S-o-b address
v5:
- add back an S-o-b tag with Daniel's Intel address

Print the name of the DRM driver when taking over fbdev devices. Makes
the output to dmesg more consistent. Note that the driver name is only
used for printing a string to the kernel log. No UAPI is affected by this
change.

Platform devices might operate on firmware framebuffers, such as VESA or
EFI. Before a native driver for the graphics hardware can take over the
device, it has to remove any platform driver that operates on the firmware
framebuffer. Aperture helpers provide the infrastructure for platform
drivers to acquire firmware framebuffers, and for native drivers to remove
them later on.
It works similar to the related fbdev mechanism. During initialization, the
platform driver acquires the firmware framebuffer's I/O memory and provides
a callback to be removed. The native driver later uses this information to
remove any platform driver for it's framebuffer I/O memory.
The aperture removal code is integrated into the existing code for removing
conflicting framebuffers, so native drivers use it automatically.
v5:
* fix build error introduced by rebasing v4
* fix typo in documentation
v4:
* hide detach callback in implementation (Daniel)
* documentation fixes
v3:
* rebase onto existing aperture infrastructure
* release aperture from list during detach; fix dangling apertures
* don't export struct drm_aperture
* document struct drm_aperture_funcs
v2:
* rename plaform helpers to aperture helpers
* tie to device lifetime with devm_ functions
* removed unsued remove() callback
* rename kickout to detach
* make struct drm_aperture private
* rebase onto existing drm_aperture.h header file
* use MIT license only for simplicity
* documentation

Platform devices might operate on firmware framebuffers, such as VESA
or EFI. Before a native driver for the graphics hardware can take over
the device, it has to remove any platform driver that operates on the
firmware framebuffer. Aperture helpers provide the infrastructure for
native drivers to remove the generic ones.
For now, this only concerns generic fbdev drivers. Code for removing
these is provided by drm_fb_helper_remove_conflicting_framebuffers() et
al. Simply wrap these functions for now. At a later point, code can be
added for generic DRM drivers to acquire firmware framebuffers.
v2:
* fix docs for drm_aperture_remove_framebuffers()
