[PATCH V3] ARM: tegra: cpuidle: remove redundant parameters for powered-down mode

[Joseph Lo]

After the patch series for system suspending support, tegra_idle_lp2_last()
no longer uses its parameters cpu_on_time or cpu_off_time, so remove them.

V3:
* no change
V2:
* rebased on the top of "ARM: tegra: add clock source for PMC" and "ARM:
  tegra: add platform suspend support"
* no physical change from V1

Applied to Tegra's for-3.10/soc branch.
