ARM: tegra11: clock: Allow EMC rates above PLLM boot rate
Added kernel command line parameter "emc_max_dvfs". If this parameter
is set, and PLLM scaling is enabled, then EMC rate may exceed boot
PLLM frequency and reach maximum accepted rate in the EMC DVFS table.
Otherwise, EMC scaling rates are limited by boot PLLM rate (this is
backward compatible with current EMC maximum rate limitations).
