[PATCH 1/3] Input: ad7877 - Convert to dev_pm_ops

[Mark Brown <broonie@opensource.wolfsonmicro.com>]

There is a move to deprecate bus-specific PM operations and move to
using dev_pm_ops instead in order to reduce the amount of boilerplate
code in buses and facilitiate updates to the PM core. Do this move for
the ad7879 SPI driver.
