Use the SIMPLE_DEV_PM_OPS() macro instead of populating a struct
dev_pm_ops directly. The suspend and resume functions will now be used
for both hibernation and suspend to ram.
If power management is disabled, SIMPLE_DEV_PM_OPS() evaluates to
nothing, The two functions won't be used and won't be included in the
kernel. Mark them as __maybe_unused to clarify that this is intended
behaviour.
With these modifications in place, we don't need the #ifdefs for power
management any more.

The driver is ported from Freescale's Linux git and can be
found in the
vendor/freescale/imx_2.6.35_maintain
branch.
The driver supports both RNG version C that's part of some Freescale
i.MX3 SoCs and version B that is available on i.MX2x chipsets.
