[PATCH 05/14] ARM: call reset_controller_of_init from default time_init handler

Some DT ARM platforms need the reset controllers to be initialized before
the timers.
This is the case of the stm32 and sunxi platforms.

This patch adds a call to reset_controller_of_init() to the default
.init_time callback when RESET_CONTROLLER is used by the platform.
