Subject: [PATCH v3] clk: qoriq: add support for lx2160a

From: Yogesh Gaur <yogeshnarayan.gaur@....com>

Add clockgen support and configuration for NXP SoC lx2160a in qoriq
clock driver with compatible property as "fsl,lx2160a-clockgen".

qoriq-cpufreq driver is based on qoriq clock driver, enable support
of NXP SoC lx2160a in qoriq cpufreq driver to handle the lx2160a SoC.
