[PATCH] ARM: imx6: pm: declare pm domain latency on power_state struct.

From: Axel Haslam <ahaslam+renesas at baylibre.com>

The generic_pm_domain structure uses an array of latencies to be able to
declare multiple intermediate states.

Declare a single "OFF" state with the default latencies So that the
power_off_latency_ns and power_on_latency_ns fields of generic_pm_domain
structure can be eventualy removed.
