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 actually managed function
pcim_iomap_range().
Fixes: 8558de401b5f ("drm/vboxvideo: use managed pci functions")
