ACPI: video: Change Sony Vaio VPCEH3U1E quirk to force_native
According to: https://bugzilla.kernel.org/show_bug.cgi?id=202401 the Sony Vaio VPCEH3U1E quirk was added to disable the acpi_video0 backlight interface because that was not working, so that userspace will pick the actually working native nv_backlight interface instead. With the new kernel behavior of hiding native interfaces unless acpi_video_get_backlight_type() returns native, the current video_detect_force_vendor quirk will cause the working nv_backlight interface will be disabled too. Change the quirk to video_detect_force_native to get the desired result of only registering the nv_backlight interface. After this all currently remaining force_vendor quirks in video_detect_dmi_table[] are there to prefer a vendor interface over a non working ACPI video interface, add a comment to document this.
