Instead of updating it each time the address changes,
just drop it completely treewide.

The common bootm code used to load uImage contents to SDRAM
before calling into the handlers if possible. This makes the
handlers complicated since they have to handle many cases. Instead,
introduce a helper to load the os after the handlers have figured
out a good load address.

We currently use the environment variable 'bootargs' to get the
Linux bootargs. This patch allows for a more flexible bootargs
generation using global variables. With it the Linux bootargs
are concatenated from multiple variables. This allows to replace
parts of the bootargs string without having to reconstruct it
completely.
With this bootargs can be constructed like:
global linux.bootargs.base="console=ttyS0,115200"
global linux.bootargs.ip="ip=dhcp"
global linux.mtdparts="physmap-flash.0:512K(nor0.barebox),-(root)"
This will then automatically be combined into a kernel bootargs
string during boot.
If the 'linux.bootargs.' variables are all empty the old standard
'bootargs' way will be used.

This switches the bootm code to the new uimage code. Also
bootm can now handle other types of images than uImages.
Currently the only architecture making use of this is
arm which allows to boot zImages, raw images and barebox
images.
I intended to make a more bisectable series from this but
I failed becuase there are many dependencies and no matter
how I tried the patches grew bigger and and bigger. So I
decided to put this all in a single patch.

All handlers used to just relocate the image without any checks, so
we are doomed if we write outside of SDRAM or will overwrite ourselves.
Move the relocation up to the generic part where we have a chance
of catching these issues.

We never had interrupt support in barebox and we have no plans to
add interrupt support. Even if we do I doubt the current fragments
of irq support are helpful, so remove them.

To allow for some generic io accessors introduce io.h and use
this instead of asm/io.h throughout the tree.
