In the upcoming multi image build process we will cat images together.
To find the concatenated image we need to reliably find the end of the
current binary. This adds a dummy section at the end of a pbl binary.
Its only purpose is to mark the end of the image. The multi image
patches will add something to this section so that it doesn't get
discarded by the linker.

Add barebox-data section in arm branch to get complete
barebox regions in sdram regions tree.

This allows for creating a lzo compressed binary unsing the pbl.
Only copy the piggydata if needed.
Add CONFIG_PBL_FORCE_PIGGYDATA_COPY option
In some case we need to copy the PIGGYDATA as the link address
as example we run from SRAM and shutdown the SDRAM/DDR for
reconfiguration but most of the time we just need to copy the
executable code.

this allow to check we do not exceed the size of the SRAM as example
introduce BAREBOX_MAX_BARE_INIT_SIZE the maximum size of bare_init
this will allow your bare_init will fit in SRAM as example
ARCH can overwrite it via ARCH_BAREBOX_MAX_BARE_INIT_SIZE

This is useful to detect a barebox image and to be able
to copy only the image size if barebox is stored on
raw partitions which are bigger than the image.
