[PATCH v3 08/11] dt-bindings: add binding for A64 DE2 CCU SRAM

[Icenowy Zheng]

A64's Display Engine 2.0 needs a section of SRAM (SRAM C) to be claimed,
otherwise the whole DE2 memory zone cannot be accessed (kept to all 0).

Add binding for this, in order to make the DE2 CCU able to claim the
SRAM and enable access to the DE2 clock and reset registers.
