This adds the necessary ACPI ID for Intel Meteor Lake IOM devices.
The callback function is_memory() is modified so that it also checks if the resource descriptor passed to it is a memory type "Address Space Resource Descriptor".
On Intel Meteor Lake the ACPI memory resource is not described using the "32-bit Memory Range Descriptor" because the memory is outside of the 32-bit address space. The memory resource is described using the "Address Space Resource Descriptor" instead.
Intel Meteor Lake is the first platform to describe the memory resource for this device with Address Space Resource Descriptor, but it most likely will not be the last. Therefore the change to the is_memory() callback function is made generic.
