Subject: [PATCH 4.9 100/125] of: fix missing kobject init for !SYSFS && OF_DYNAMIC config

From: Rob Herring <robh@...nel.org>

[ Upstream commit bd82bbf38cbe27f2c65660da801900d71bcc5cc8 ]

The ref counting is broken for OF_DYNAMIC when sysfs is disabled because
the kobject initialization is skipped. Only the properties
add/remove/update should be skipped for !SYSFS config.
