OMAP: PM: omap_device: fix device power domain callbacks

After commit 4d27e9dcff00a6425d779b065ec8892e4f391661 (PM: Make power
domain callbacks take precedence over subsystem ones), the power
domain callbacks need to call the driver callbacks instead of relying
on the default subsystem (in this case, platform_bus) to handle the
driver callbacks.

Validated on 3430/n900, 3530/Overo.
