PATCH v2 1/1 ARM: OMAP2+: omap2plus_defconfig: enable devtmpfs and automount

Since udev-176 [1], udev no longer creates device nodes under /dev and this has to be managed by the kernel devtmpfs filesystem.

This makes devtmpfs filesystem a requirement on newer systems and a kernel built with the current OMAP2+ config will not boot on them.

Also, it is good to have devtmpfs at /dev automount enabled by default.
