After commit 02c057ddefef ("ACPI: video: Convert the driver to a
platform one") the driver_data pointer in the ACPI companion device
object is not cleared automatically on driver remove any more, so
clear it directly in acpi_video_bus_remove().

Fixes: 02c057ddefef ("ACPI: video: Convert the driver to a platform one")
