Revert "Revert "Revert "drivercore: Avoid adding devices without pm_ops to dpm list"""

This reverts commit 04f65062030f157e8b7081b837e3121aeb2162a2.

Not able to add device with PM core and causing suspend/resume
issue in I2C client driver.pm_ops are removed from I2C bus type
and should fall back on client driver pm_ops.

Reverting this change as we are not able to register I2C
client devices with PM core.
