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.
