Pull this out of #ifdef block and kill entire #else/endif along with
WM97XX_PM_OPS define: SIMPLE_DEV_PM_OPS will result in an empty
structure if CONFIG_PM_SLEEP is not set.

It will create a struct dev_pm_ops full of NULLs. That's kind of
counterproductive to removing PM related data and functions from the kernel
if PM support is no enabled.

Indeed, a major goal of disabling PM support is to save space.
