Subject: [PATCH v2 25/29] arm64: dts: realtek: rtd129x: Add eFuse package_id to chip-info

Add the package_id field as sub-node to eFuse and reference it for
chip identification.

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

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