of: fix missing kobject init for !SYSFS && OF_DYNAMIC config

BugLink: https://bugs.launchpad.net/bugs/1875905

[ Upstream commit bd82bbf3 ]

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.
