Adding a flag for tegra_disable_clean_inv_dcache to flush cache as LoUIS or ALL. After this patch, the v7_flush_dcache_louis is used for CPU hotplug and CPU suspend in CPU power down (e.g. CPU idle power-down mode) case. And the v7_flush_dcache_all is used for CPU cluster power down (e.g. suspend to LP2 mode).

Is there a reason those two values aren't just 0 and 1; they only seem to be used internally to switch between two function calls, and not passed to those calls or written to HW.
