Marc Gonzalez 9dbd224f9e cpufreq: dt: Don't use generic platdev driver for tango
On tango platforms, firmware configures the CPU clock, and Linux is
then only allowed to use the cpu_clk_divider to change the frequency.
Build the OPP table dynamically at init, in order to support whatever
firmware throws at us.
