The {acpi_}device_init() and device_get_class() functions are identical across
Arm and RISC-V, and they are likely to remain the same for other architectures
like PPC.
Since there is no architecture-specific logic within these functions, they are
good candidates to be moved to the common codebase.

This patch series refactors the code by moving these functions to the common
directory, reducing code duplication and simplifying future maintenance.

---
Changes in V3:
 - drop _SECTIONS from the name of the macros ADEV_INFO and DT_DEV_INFO
 - update the definion of macros ADEV_INFO and DT_DEV_INFO
 - drop DEVICE_INIT config.
---
Changes in v2:
 - Introduce macros for definition of ACPI and Device Tree sections.
 - Introduce CONFIG_DEVICE_INIT to make common/device.o compilable only for Arm,
   PPC and RISC-V.
