gemini: fix hard disk boot on D-Link devices
Since the D-Link devices boot from hard disk we need to add the following changes to Gemini: - Supply a bootarg in the device tree so we can boot from the right partition (/dev/sda4 on DNS-313) - Disable forced command line in config so the kernel picks up the right bootargs from the device tree - Enable EXT4 in the config as this is used for rootfs else we get nowhere, we cannot load this as a module because, well, it is supposed to be loaded from the root partition (chicken and egg problem). - Enable jbd2 and mbcache (needed by ext4) Also clean out the premature attempts to dynamically modify the command line in the Image makefile: we should pass this with the device tree bootargs instead, it works much better.

+Subject: [PATCH] ARM: dts: Fix bootargs for Gemini D-Link devices
+
+These machines need to be booted from very specific harddisk
+partitions (as the D-Link DNS-313 boots specifically from
+partition 4). Add the proper bootargs so that everything works
+smoothly.
