[PATCH v4 19/19] cpufreq: pmac32-cpufreq: remove device tree parsing for cpu nodes

[Sudeep KarkadaNagesha]

From: Sudeep KarkadaNagesha <sudeep.karkadanagesha at arm.com>

Now that the cpu device registration initialises the of_node(if available)
appropriately for all the cpus, parsing here is redundant.

This patch removes DT parsing and uses cpu->of_node instead.
