ACPI: video: Drop "Samsung X360" acpi_backlight=native quirk
acpi_backlight=native is the default for the "Samsung X360", but as
the comment explains the quirk was still necessary because even
briefly registering the acpi_video0 backlight; and then unregistering
it once the native driver showed up, was leading to issues.
After the "ACPI: video: Make backlight class device registration
a separate step" patch from earlier in this patch-series, we no
longer briefly register the acpi_video0 backlight on systems where
the native driver should be used.
So this is no longer an issue an the quirk is no longer needed.
