ARM: tegra: clock: Update Tegra3 EMC clock configuration
- Moved initialization of Tegra3 dram configuration variables from
EMC DVFS setup to EMC clock initialization, so that these variables
can be used independently of DVFS.
- Added graceful exit from EMC DVFS setup in case of empty DVFS table
- Applied EMC minimum rate to direct EMC clock round rate operations
(currently applied only to shared EMC bus update).
(cherry picked from commit c6b3f6e0eb0b6e3485d02fc5306a1c09cbacf914)
