3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ricardo Martins <redacted>

commit 4f7a67e2dd49fbfba002c453bc24bf00e701cc71 upstream.

After commit aaa0ef289afe9186f81e2340114ea413eef0492a "PS3 EHCI QH
read work-around", Terratec Grabby (em28xx) stopped working with AMD
Geode LX 800 (USB controller AMD CS5536). Since this is a PS3 only
fix, the following patch adds a conditional block around it.
