The DRAM memory controller of AST2700 is not backward compatible to previous chips such AST2600, AST2500 and AST2400. Max memory is now 8GiB on the AST2700. Introduce new aspeed_2700_sdmc and class with read/write operation and reset handlers. Define DRAMC necessary protected registers and unprotected registers for AST2700 and increase the register set to 0x1000. Add unlocked property to change controller protected status. Incrementing the version of vmstate to 2.
