Subject: [PATCH v3 10/22] PM / devfreq: tegra30: Don't enable consecutive-down interrupt on startup

The consecutive-down event tells that we should perform frequency
de-boosting, but boosting is in a reset state on start and hence the
event won't do anything useful for us and it will be just a dummy
interrupt request.
