ACPI updates for 6.12-rc5

- Make acpi_parse_prmt() look for EFI_MEMORY_RUNTIME memory regions
    only to comply with the UEFI specification and make PRM use
    efi_guid_t instead of guid_t to avoid a compiler warning triggered
    by that change (Koba Ko, Dan Carpenter).
 
  - Add an ACPI IRQ override quirk for LG 16T90SP (Christian Heusel).
 
  - Add a lid switch detection quirk for Samsung Galaxy Book2 (Shubham
    Panwar).

Pull ACPI fixes from Rafael Wysocki:
 "These fix an ACPI PRM (Platform Runtime Mechanism) issue and add two
  new DMI quirks, one for an ACPI IRQ override and one for lid switch
  detection:

   - Make acpi_parse_prmt() look for EFI_MEMORY_RUNTIME memory regions
     only to comply with the UEFI specification and make PRM use
     efi_guid_t instead of guid_t to avoid a compiler warning triggered
     by that change (Koba Ko, Dan Carpenter)

   - Add an ACPI IRQ override quirk for LG 16T90SP (Christian Heusel)

   - Add a lid switch detection quirk for Samsung Galaxy Book2 (Shubham
     Panwar)"
