arm and i386 has almost the same function acpi_add_rom_blob(), except
giving different FWCfgCallback function.
This patch moves acpi_add_rom_blob() to utils.c by passing
FWCfgCallback to it.
Signed-off-by: Wei Yang <richardw.yang@linux.intel.com>

v4:
* extract -> moves
* adjust comment in source to make checkpatch happy
v3:
* put acpi_add_rom_blob() to hw/acpi/utils.c
v2:
* remove unused header in original source file

Which fw_cfg.h? There is only two fw_cfg.h in qemu.
$ find . -name fw_cfg.h
./include/hw/nvram/fw_cfg.h
./tests/libqos/fw_cfg.h
Replace hw/loader.h with hw/nvram/fw_cfg.h will fail.
Do get your point here.

Point here is to not to put in header a dependency that symbols in this header
do not need so you need a header that declares FWCfgCallback and that's all.
loader.h should go into utils.c file
