[PATCH] ACPI: video: Add backlight=native quirk for Dell OptiPlex AIO 7410 35W

[Anup Keshwani]

Dell All In One (AIO) models released after 2017 may use a backlight
controller board connected to a UART.

In DSDT this uart port will be defined as:

Name (_HID, "DELL0501")
Name (_CID, EisaId ("PNP0501")
