Merge ACPI device enumeration fixes for 6.10-rc5:

 - Ignore MIPI camera graph port nodes created with the help of the
   information from the ACPI tables on all Dell Tiger, Alder and Raptor
   Lake models as that information is reported to be invalid on the
   systems in question (Hans de Goede).

 - Use new Intel CPU model matching macros in the MIPI DisCo for Imaging
   part of ACPI device enumeration (Hans de Goede).

* acpi-scan:
  ACPI: mipi-disco-img: Switch to new Intel CPU model defines
  ACPI: scan: Ignore camera graph port nodes on all Dell Tiger, Alder and Raptor Lake models
