[PATCH] Alchemy: register mmc platform device for db1200/pb1200 boards

Subject: [PATCH] Alchemy: register mmc platform device for db1200/pb1200 boards
From: Manuel Lauss <mlau@msc-ge.com>
Date: Sat, 17 May 2008 17:48:02 +0200
Add au1xmmc platform data for PB1200/DB1200 boards, and wire up
the 2 SD controllers for them.
