- remove now unused __REG definitions
- include individual SoC register files instead of imx-regs.h
- move IMX_GPIO_NR to generic.h
- finally remove imx-regs.h

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

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.

Traditionally U-Boot and barebox have the exception vectors at
the start of the binary. There is no real reason in doing so,
because in the majority of cases this data will not be at 0x0
where it could be used as vectors directly anyway.
This patch puts the vectors into a separate linker section and
defines an head function which is placed at the start of the
image instead. Putting this in a separate function also has
the advantage that it can be placed at the start of images
which require an additional header like several Freescale i.MX
images. As the head function contains the barebox arm magic
those images can now also be detected as barebox images.

Extend DCD table and low level init routines. Add barebox SDRAM
device. Also, fix the memory size for bank 0 to 128MB. It was
accidently changed to 124MB here:

    add a add_mem_device function

    Add a helper function for boards to register their memory
    devices. This makes the board code smaller and also helps
    getting rid of map_base and struct memory_platform_data.

    And switch all of the memory to it

this will allow each arch to handle the boards more simply and depending on
there need

the env var BOARD will refer to the current board dirent

for sandbox as we have only one board the board dirent is arch/sandbox/board
