Refactor arm/xen.lds.S by replacing the inline definitions for
device info sections with the newly introduced {DT,ACPI}_DEV_INFO
macros from xen/xen.lds.h.

Change alignment of DT_DEV_INFO and ACPI_DEV_INFO sections from
8 to POINTER_ALIGN as struct acpi_device_desc and struct device_desc
don't have any uint64_t's so it is safe to do that.
