Okay, per the documentation "imply" is the preferred way over "default y && depends on". Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

Per the kconfig.rst: A device should be listed [...] ``imply`` if (depending on the QEMU command line) the board may or may not be started without it. This is the case with the NVDIMM device (it is certainly possible to start a machine without NVDIMM) , so use the 'imply' weak reverse dependency to select the symbol.
