[PATCH 5.19 121/155] usb: typec: intel_pmc_mux: Add new ACPI ID for Meteor Lake IOM device

[Greg Kroah-Hartman]

From: Utkarsh Patel <utkarsh.h.patel@xxxxxxxxx>

commit 1b1b672cc1d4fb3065dac79efb8901bd6244ef69 upstream.

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.
