Log: Add plug and play information macroses for ACPI and I2C buses. Matching table format is compatible with ACPI_ID_PROBE bus method. Note that while ACPI_ID_PROBE matches against _HID and all _CIDs, current acpi_pnpinfo_str() exports only _HID and first _CID. That means second and further _CIDs should be added to both acpi_pnpinfo_str() and ACPICOMPAT_PNP_INFO if device matching against them is required.
