Add a new cpufreq driver for Tegra124. Instead of using the PLLX as the CPU clocksource, switch immediately to the DFLL. It allows the use of higher clock rates, and will automatically scale the CPU voltage as well. Besides the CPU clocksource switch, we let the cpufreq-cpu0 driver for all the cpufreq operations. This driver also relies on the DFLL driver to fill the OPP table for the CPU0 device, so that the cpufreq-cpu0 driver knows what frequencies to use.
