operations, like directly calling outb/inb and using some inline
assembly code which prevents it being ported to other architectures.
This patch adds callback functions and moves those to arch/x86/

The qemu_fwcfg_free_files() function is only used in error handling in
ACPI table generation, let's not make this a core function and move it
to the right place.

This patch adds the ability to load and link ACPI tables provided by QEMU.
QEMU tells guests how to load and patch ACPI tables through its fw_cfg
interface, by adding a firmware file 'etc/table-loader'. Guests are
supposed to parse this file and execute corresponding QEMU commands.
