Merge: Enable and update gpio-keys-polled driver

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/4918

JIRA: https://issues.redhat.com/browse/RHEL-52234  
  
We've been requested to enable this driver because there are vendors  
using it (although not all DT files are upstream yet).  
  
I've performed basic testing on the Jetson AGX Orin w/ a slightly  
modified driver (so that it would load without DT changes).
