ARM: mx53: Allow suspend/resume
Current imx53_pm_init() implementation is incomplete as it lacks calling
suspend_set_ops().
Use a single imx5_pm_init() function to handle both mx51 and mx53.
This allows mx53 to enter in low-power mode.
Tested on a mx53qsb:
root@freescale /$ echo mem > /sys/power/state
