ARM: tegra3: power: Add LP2 power mode support for CPU 0
Add support for forced Tegra3 LP2 low power mode on the boot processor
(CPU 0) via the cluster control interface when all others are offline.
Switching to the LP CPU mode is also enabled with this change.
LP2 in idle and LP2 mode on the secondary processors is not yet
supported.
