imx233: speedup charging trickle phase

Browse source 
Per Freescale recommandation, we need to ramp up the 4.2V rail before enabling
charging. Ramping should be done at 1 step/10ms, but the old code did 1 step/1s
because the powermgmt_step() function is called once every second. Use a tick
task to ramp up much faster.
