ramfb: add migration support
Implementing RAMFB migration is quite straightforward. One caveat is to
treat the whole RAMFBCfg as a blob, since that's what is exposed to the
guest directly. This avoid having to fiddle with endianness issues if we
were to migrate fields individually as integers.
The devices using RAMFB will have to include ramfb_vmstate in their
migration description.
