[PATCH v4 5/6] xen/riscv: add section for device information in linker script

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

Introduce a new `.dev.info` section in the RISC-V 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.
