Enable and update gpio-keys-polled driver

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).
