Subject: [PATCH 1/7] ARM: at91: at91rm9200: set idle and restart from rm9200_dt_device_init()

From: Alexandre Belloni <alexandre.belloni@...e-electrons.com>

Setup arm_pm_idle and arm_pm_restart function pointers from
rm9200_dt_device_init() function to simplify the at91rm9200 initialization
process.
This same move is already done for the sam9s.
