vga: convert vga and its derivatives to the memory API

Convert all vga memory to the memory API.  Note we need to fall back to
get_system_memory(), since the various buses don't pass the vga window
as a memory region.

We no longer need to sync the dirty bitmap of the cirrus mapped memory
banks, since the memory API takes care of that for us.
