loader: drop return value for rom_add_blob_fixed

rom_add_blob never fails, and neither does rom_add_blob_fixed,
so there's no need to return value from it.

In fact, rom_add_blob_fixed was erroneously returning -1 unconditionally
which made the only system that checked the return value -M bamboo fail...

loader: support for unmapped ROM blobs

Support ROM blobs not mapped into guest memory:
same as ROM files really but use caller's buffer.

Support invoking callback on access and
return memory pointer making it easier
for caller to update memory if necessary....

loader: store FW CFG ROM files in RAM

ROM files that are put in FW CFG are copied to guest ram, by BIOS, but
they are not backed by RAM so they don't get migrated.

Each time we change two bytes in such a ROM this breaks cross-version
migration: since we can migrate after BIOS has read the first byte but...

hw/loader: Support ramdisk with u-boot header

Introduce 'load_ramdisk()' which can load "normal" ramdisks and ramdisks
with a u-boot header.
To enable this and leverage synergies 'load_uimage()' is refactored to
accomodate this additional use case.

refer to FWCfgState explicitly

Currently some places use pointer-to-void even though they mean
pointer-to-FWCfgState. Clean them up.

hw: move headers to include/

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches....
