Subject: Add radeon suspend/resume quirk for HP Compaq dc5750.

From: Jeffery Miller <[email protected]>

commit 09bfda10e6efd7b65bcc29237bee1765ed779657 upstream.

With the radeon driver loaded the HP Compaq dc5750 Small Form Factor machine fails to resume from suspend. Adding a quirk similar to other devices avoids the problem and the system resumes properly.
