The use of ti,twl4030-power-reset is recommended at least on
3530 that needs a special configuration for warm reset to work.
+When using ti,twl4030-power-idle, the TI recommended configuration

- ti,use_poweroff: With this flag, the chip will initiates an ACTIVE-to-OFF or
SLEEP-to-OFF transition when the system poweroffs.
