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.
Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done.
Suspending console(s) (use no_console_suspend to debug)
... (Press Power button)
PM: suspend of devices complete after 17.067 msecs
PM: suspend devices took 0.020 seconds
PM: late suspend of devices complete after 0.954 msecs
PM: noirq suspend of devices complete after 1.288 msecs
Disabling non-boot CPUs ...
PM: noirq resume of devices complete after 0.680 msecs
PM: early resume of devices complete after 0.914 msecs
PM: resume of devices complete after 44.955 msecs
PM: resume devices took 0.050 seconds
Restarting tasks ... done.
mmc0: host does not support reading read-only switch. assuming write-enable.
mmc0: new SDHC card at address e624
mmcblk0: mmc0:e624 SU04G 3.69 GiB
