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 PM: Syncing filesystems ... done. mmc0: card e624 removed Freezing user space processes ... (elapsed 0.001 seconds) done.
