It will be used by followup patches to switch from creating AML in ad-hoc way to a more systematic one that will scan present devices and ask them to provide their AML code like it's done with ISA devices. This patch is a partial conversion, as it only fetches AML from slave devices attached to its I2C bus. The conversion will be completed when PCI bus is switched to use AcpiDevAmlIf and build_smb0() could be dropped.
