When the PCI devres API was introduced to this driver, it was wrongly
assumed that initializing the device with pcim_enable_device() instead of
pci_enable_device() will make all PCI functions managed.
This is wrong and was caused by the quite confusing PCI devres API in which
some, but not all, functions become managed that way.
The function pci_iomap_range() is never managed.
Replace pci_iomap_range() with the managed function pcim_iomap_range().

The vboxvideo driver provides struct drm_framebuffer_funcs.dirty_fb from
its own implementation. Switch over to drm_atomic_helper_dirty_fb() and
handle screen updates in the primary plane's atomic_update function.
With dirty_fb out of the way, we can further replace struct vbox_frammebuffer
with generic code.

The data structure |struct drm_vram_mm| and its helpers replace vboxvideo's
TTM-based memory manager. It's the same implementation; except for the type
names.
v4:
* don't select DRM_TTM or DRM_VRAM_MM_HELPER
v3:
* use drm_gem_vram_mm_funcs
* convert driver to drm_device-based instance
v2:
* implement vbox_mmap() with drm_vram_mm_mmap()

This patch replaces |struct vbox_bo| and its helpers with the generic
implementation of |struct drm_gem_vram_object|. The only change in
semantics is that &ttm_bo_driver.verify_access() now does the actual
verification.
v4:
* select config option DRM_VRAM_HELPER
v3:
* remove forward declaration of struct vbox_gem_object
v2:
nothing
