    xen: define ACPI and DT device info sections macros
    
    Introduce macros to define device information sections based on
    the configuration of ACPI or device tree support. These sections
    are required for common code of device initialization and getting
    an information about a device.
    
    These macros are expected to be used across different
    architectures (Arm, PPC, RISC-V), so they are moved to
    the common xen/xen.lds.h, based on their original definition
    in Arm.
