ARM: dts: msm: configure interrupt types for charger for pm660

Currently the interrupt trigger type is configured as NONE. This
causes a level handler to be assigned to these interrupts.

However, all of them are edge triggered interrupts with varying
falling/rising/both edge flavors. Update the device tree to
use their correct trigger types thereby preventing missed interrupt
storms because of incorrect handler types.
