From: Igor Opaniuk <igor.opaniuk at foundries.io>
Add support for "rpmb-dev" property which provides eMMC phandle
for RPMB-related operations.
This commit is created only to show DT node updates for RFC patch,
obviously that node should be updated in device-tree-bindings in
Linux first, that pulled here.
