[PATCH 1/2] ARM: vexpress: Make defconfig work again

[Pawel Moll]

From: Fathi Boudra <fathi.boudra at linaro.org>

This patch updates the Versatile Express defconfig to a level
which makes it possible to run a defconfig-ed kernel work
on the board and in QEMU with modern userspace. It does:

- update cmdline to contain "console=ttyAMA0" only
- enable devtmpfs filesystem
- enable voltage regulator support
- enable ext4 filesystem
- disable low level debug and early printk

Signed-off-by: Fathi Boudra <fathi.boudra at linaro.org>
[PM: removed DEBUG_LL - it doesn't work on qemu]
[PM: reworded the commit message]
