[PATCH] iio: mma8452: Simplify the PM related hooks

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

We do not need to define MMA8452_PM_OPS as SIMPLE_DEV_PM_OPS handles the 
CONFIG_PM_SLEEP=n case just fine.

While at it get rid of the PM related ifdef's by marking the suspend/resume
functions as '__maybe_unused'.
