milkymist-softusb: Don't map RAM memory regions in the device itself
Don't map the pmem and dmem RAM memory regions in the milkymist-softusb
device itself. Instead just expose them as sysbus mmio regions which
the device creator can map appropriately. This allows us to drop the
pmem_base and dmem_base properties. Instead of going via
cpu_physical_memory_read/_write when the device wants to access the
RAMs, we just keep a host pointer to the memory and use that.
