qemu_ram_alloc: Add DeviceState and name parameters

These will be used to generate unique id strings for ramblocks.  The name
field is required, the device pointer is optional as most callers don't
have a device.  When there's no device or the device isn't a child of
a bus implementing BusInfo.get_dev_path, the name should be unique for
the platform.
