Vboxguest fixes

Hans de Goederequested to merge
jwrdegoede/kernel-ark:vboxguest-fixes into ark-patches

VirtualBox upstream has added a new ioctl to their out of tree driver implementring the /dev/vboxguest device in the VirtualBox 6.1.x series. Without this ioctl being supported automatic resizing of the guest resolution to match the Window size does not work when using the VMSVGA virtual GPU which is the default GPU for new VMs under VirtualBox 6.1.x .

This series has been posted upstream here: https://lore.kernel.org/lkml/20200520195440.38759-1-hdegoede@redhat.com/

This patch series adds support for the new ioctl, fixing the resizing issue.

Note these patches have already been added to the Fedora 5.6.x kernels.
