tegra pmu: do not turn ON the LDO0 rail by default
The LDO0 power rail was enabled during bootup by default, thereby
increasing the ref count. This results in the rail remaining powered
ON even when we try to disable it from a driver.
Disabling the LDO0 by default, when there are no devices actively
using it, should result in power saving.
