Revert "ACPICA: revert "acpi_serialize" changes"

This reverts commit a8f4af6dc6600980885c594f52eecd60edd62013.
Thus restoring ACPICA's new acpi_serialize code.

This commit by itself may cause a regression, but
it is reverted in this order so that subsequent
reverts reverts under this one can be made
without conflict.
