ACPI: bus: add stub acpi_dev_found() to linux/acpi.h
acpi_dev_found() will be used to detect if a given ACPI device is in the system. It will be compiled in non-ACPI case, but the function is in acpi_bus.h and acpi_bus.h can only be used in ACPI case, so this patch add the stub function to linux/acpi.h to make compiled successfully in non-ACPI cases.
