dt-bindings: mfd: Document smp-memram subnode for aspeed,ast2x00-scu
The platform initialisation code for the AST2600 implements the custom SMP bringup protocol, and searches for the relevant compatible. As a consequence, define the requisite node and the compatible string, which in-turn tidies up the dtb check results.
