[PATCHv3 3/3] ARM: dts: socfpga: memreserve first 4KB for future system use

[dinguyen-yzvPICuk2ABMcg4IHK0kFoH6Mc4MB0Vx]

From: Dinh Nguyen <dinguyen-yzvPICuk2ABMcg4IHK0kFoH6Mc4MB0Vx@public.gmane.org>

This patch adds a /memreserve/ section to reserve the first 4K for future
use by the system. One possible use-case is trampoline code used to bring
secondary cores online.
