ARM: dts: berlin: add broken-cd and set bus width for eMMC in Marvell DMP DT

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.
