Input: eeti_ts - convert to dev_pm_ops

There is a general move towards the use of dev_pm_ops rather than
bus specific suspend APIs as this simplifies both the bus and PM core
implementations. Convert the eeti_ts driver over.

Compile tested only by me, but Sven Neumann reports that the new code
works.
