ARM: tegra: dvfs: Handle Tegra3 alternative dvfs errors
Propagate error to the caller when switching between alternative
cpu dvfs tables. Change dvfs table during cpu hotplug operation
only after the new edp limit is set, and abort bringing cpu core
on-line in case of failure in applying new (less conservative)
table. When cpu core is removed change dvfs table before setting
new edp limit, and ignore error (it is safe to continue with more
conservative table).
