Subject: [PATCH v2 24/29] dt-bindings: soc: realtek: rtd1195-chip: Allow nvmem-cells property

Allow to optionally specify nvmem cells to identify the chip.
RTD1295 family will want the eFuse package_id cell.

Signed-off-by: Andreas Färber <afaerber@...e.de>

 v1 -> v2:
 * Instead of extending reg, allow nvmem-cells reference for eFuse
