Add an implementation of the DBG2 (Debug Port Table 2) ACPI table. Adjust one of the header includes to be in the correct order, before adding more. Note that the DBG2 table is generic but the PCI UART is x86-specific at present since it assumes an ns16550 UART. It can be generalised later if necessary.
