Subject: [PATCH 3.18 171/183] ARM: dts: berlin: add broken-cd and set bus width for eMMC in Marvell DMP DT

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

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

From: Jisheng Zhang <jszhang@...vell.com>

commit 5adba7c2daaecccf377e7ed5a2996caedd5384f1 upstream.

There's no card detection for the eMMC, so this patch adds the missing
broken-cd property. This patch also sets bus width as 8 to add
MMC_CAP_8_BIT_DATA in the Host capabilities.

Fixes: 3047086dfd56 ("ARM: dts: berlin: enable SD card reader and eMMC for the BG2Q DMP")
