Introduce a new `.dev.info` section in the PPC linker script to
handle device-specific information. This section is required by
common code (common/device.c: device_init(), device_get_class() ).
This section is aligned to `POINTER_ALIGN`, with `_sdevice` and `_edevice`
marking the start and end of the section, respectively.

Changes in V2:
 - reuse DT_DEV_INFO_SEC introduced earlier in this patch series with using
   of DECL_SECTION.
