[PATCH 4.2 106/120] ARM: BCM63xx: fix parameter to of_get_cpu_node in bcm63138_smp_boot_secondary

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
