[PATCH v2 1/2] xen/riscv: initialize bootinfo from dtb

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

Parse DTB during startup, allowing memory banks and reserved
memory regions to be set up, along with early device tree node
( chosen, "xen,domain", "reserved-memory", etc  ) handling.

Signed-off-by: Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>

Changes in V2:
 - Drop local variable fdt_size as it is going to be used only once.
