x86: qemu: add the ability to load and link ACPI tables from QEMU

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.

This patch adds a parameter to the function setup_early_uart() to either

setup_early_uart() does not match its functionality any more, lets
rename it to setup_internal_uart() as well in this patch.
