ACPI: scan: Ignore camera graph port nodes on all Dell Tiger, Alder and Raptor Lake models

Dell laptops with IPU6 camera (the Tiger Lake, Alder Lake and Raptor
Lake generations) have broken ACPI MIPI DISCO information (this results
from an OEM attempt to make Linux work by supplying it with custom data
in the ACPI tables which has never been supported in the mainline).

Instead of adding a lot of DMI quirks for this, check for Dell platforms
based on the processor generations in question and drop the ACPI graph
port nodes, likely to be created with the help of invalid data, on all
of them.
