Introduce conditional 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.
