Subject: [patch net-next 06/11] ACPI: bus: move acpi_match_device_ids() to linux/acpi.h

From: Hanjun Guo <hanjun.guo@...aro.org>

acpi_match_device_ids() will be used for drivers to match
different hardware versions, it will be compiled in non-ACPI
case, but acpi_match_device_ids() in acpi_bus.h and it can
only be used in ACPI case, so move it to linux/acpi.h and
introduce a stub function for it.
