ARM: tegra11x: Add flag to force C0NC power gating
The bit 2 of fast_cluster_power_down_mode now dictates whether to
force the power down mode specified in b[0-1]. If bit 2 is 0, then
b[0-1] specifies the deepest cluster power state in idle, the cluster
idle power state doesn't need to go to that level every time. If bit
2 is 1, then b[0-1] forces cluster idle power state to that level.
