ARM: tegra: power: Re-initialize Tegra3 EMC after LP0
Since EMC frequency is not restored after exit from LP0, re-initialize
EMC clock with the new warm boot configuration, and make sure that the
1st after LP0 clock change does not use stale timing cache.
Skip Tegra2 specific EMC restoration on Tegra3 platforms.
