[PATCH] dt-bindings: media: Add sram-size Property for Wave5

[Brandon Brnich]

Wave521c has capability to use SRAM carveout to store reference data with
purpose of reducing memory bandwidth. To properly use this pool, the driver
expects to have an sram and sram-size node. Without sram-size node, driver
will default value to zero, making sram node irrelevant.
