I didn't know it has moved.

The old address has been archived by archive.org/web at the following
address:
https://web.archive.org/web/20190826025113/https://cache.freescale.com/files/32bit/doc/ref_manual/IMX6DQRM.pdf

The Linux kernel has a unique link to this document at this URL:
http://www.nxp.com/assets/documents/data/en/reference-manuals/IMX6DQRM.pdf

And it's the same since since 2017, and it was introduced by this
commit:

However that redirects to https://www.nxp.com/doc/IMX6DQRM which
redirects to a login page.

Archive.org/web has many links for that page, but I only found one of
them to work, which is older than the archive of the link I had: 
https://web.archive.org/web/20180829173128/https://www.nxp.com/docs/en/reference-manual/IMX6DQRM.pdf

I'm not aware of any project tracking datasheet / reference manual URLs
and versions though, but it would probably be something very useful to
have.

At some point, I plan to see if it's possible to something like that
with Wikidata, but I'm not sure if it's fit to track datasheets URLs
over time.
