ACPI: video: Drop NL5x?U, PF4NU1F and PF5?U?? acpi_backlight=native quirks

acpi_backlight=native is the default for these, 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 quirks are no longer needed.
