Subject: [PATCH] u8500_defconfig: allow creation and mounting of devtmpfs

This patch enables CONFIG_DETTMPFS and CONFIG_DEVTMPFS_MOUNT
flags for u8500 based devices.

In this way it's possible to create a tmpfs/ramfs already in the
early stages of the boot, allowing programs like udev/mdev to
populate the /dev directory.
