Subject: [char-misc-next] mei: pxp: match against PCI_CLASS_DISPLAY_OTHER

From: Daniele Ceraolo Spurio <[email protected]>

The ATS-M class is PCI_CLASS_DISPLAY_OTHER instead of
PCI_CLASS_DISPLAY_VGA, so we need to match against that class as well.
The matching is still restricted to Intel devices only.

Fixes: ceeedd951f8a ("mei: pxp: match without driver name")
