Adding cclpex node to represent Tegra234 cpufreq.
Tegra234 uses some of the CRAB (Control Register Access Bus)
registers for cpu frequency requests. These registers are
memory mapped to CCPLEX_MMCRAB_ARM region. In this node, mapping
the range of MMCRAB registers required only for cpu frequency info.
