Since kernel 4.16 the memory nodes got a @<reg> suffix so the fixup
won't work correctly anymore, because instead of adapting the extisting
one the fixup creates a new node and keeps the old (maybe incorrect)
node.
To be compatible with the old and new layout delete the found memory
node and create a new one. The new node follows the new @<reg> style.
The patch also renames the node parameter to make it clearer.

The bootm code needs to put the Kernel image and initrd into free
RAM. Add some functions to find free RAM chunks to help this code.

If drivers want to fixup their specific instance they need some context
to know which instance they have to fixup.

Fix size address calculation.
Global variables from <asm/sections.h> which are defined
in linker script *.lds files for end addresses has already
a +1 calculation.
For example:
stext = 0x100 with a size about 0x50 will result a etext = 0x150.
In this case a correct size calculation is (etext - stext) = 0x50.
In function 'request_sdram_region' the end address will be
calculated with (start + size - 1) which result a correct
end address of 0x149 in this example.

When a memory bank is already registered, return an error code
instead of throwing a bug. This can happen if a board has registered
a memory bank and the same bank is then probed from the devicetree.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

Storing the size instead of the resource end in struct resource was
a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously
leads to problems. 'end' on the other hand will never exceed
UINT[32|64]_MAX. Also this way we can express a iomem region covering
the whole address space.

Thanks to a common memory handling barebox knows the sdram banks
and sizes, so we can add a common fixup functions for the nodes
in the devicetree.

On arm we have the concept of memory banks which can
be registered and iterated over. This is useful for
other architectures aswell, so add some generic infrastructure
for this.

These functions are needed independently of the specific
malloc implementation, so move them out.
