With CONFIG_MMU_EARLY enabled the board does not survive the call
to imx53_init_lowlevel(). This should not happen, but the reasons
are currently unknown. This works on other boards like the i.MX53
QSB.
This patch moves the call to imx53_init_lowlevel to
barebox_arm_reset_vector() which is executed with MMU disabled.

The second UART is used on the mba53 baseboard. The first UART is only
used on custom hardware. This patch changes the UART to the one used
on the freely available baseboard.

Having the board config file in /env/init has the problem that
the settings in /env/config are overwritten in the init sequence.
This moves the config-board files to /env/ and sources them explicitly
from /env/bin/init before sourcing /env/config

reset is confusing with the cpu reset and impossible to grep

Most i.MX boards can use the imx*_barebox_entry functions. The remaining
(i.MX21, i.MX6) use hardcoded base addresses.

The idea of having /env/init/* scripts was to make the configuration
more flexible and customizable for boards. It turned out though that
people (including myself) do not find the place where they should
change these settings.
So this patch brings back /env/config for defenv-2. The individual
env/init/* scripts are removed and their content is added to
/env/init/config-board. This makes the values from /env/init/config-board
the board specific defaults which can be overwritten in /env/config.

With pbl support enabled most boards need a pbl-y for their lowlevel
stuff.

With compressed image support TEXT_BASE will become the base
address of the uncompressed image. What the boards want instead
is the base address of the decompressor code or, if not compressed,
the base address of the uncompressed image. Use _text which is
the correct one for both cases.

The exception vector table will become part of the uncompressed image,
so we can't reference them from the lowlevel init stuff anymore.

This means using an uint64_t instead of a struct pad_desc which allows
us to change pad settings using logic operations. Also with this we
can more easily keep the iomux tables in sync with the kernel.

The image sizes have been hardcoded to 256K. This is inefficient
for smaller images and nonfunctional for bigger images. Calculate
the image size during compile time and use it.
