gemini: fix hard disk boot on D-Link devices

Browse source 
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.
