[RFC PATCH v2 09/15] cpufreq: highbank-cpufreq: remove device tree parsing for cpu nodes

[Sudeep.KarkadaNagesha at arm.com]

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 all DT parsing and uses cpu->of_node instead.
