4.2-stable review patch. If anyone has any objections, please let me know.

From: Sudeep Holla <sudeep.holla@arm.com>
commit a6b4b25bd15c0a490769422a7eee355e9e91a57b upstream.
of_get_cpu_node provides the device node associated with the given logical CPU and cpu_logical_map contains the physical id for each CPU in the logical ordering. Passing cpu_logical_map(cpu) to of_get_cpu_node is incorrect.
This patch fixes the issue by passing the logical CPU number to of_get_cpu_node
