We are missing pm_runtime_disable() in 2430 glue layer. Further,
we only need to enable PM runtime and disable it on exit. With
musb_core.c doing PM, the glue layer as a parent will always be
active when musb_core.c is active.
This fixes host enumeration issues with some devices as reported
by Ladislav Michl <ladis@xxxxxxxxxxxxxx>.
If changes are needed to the autosuspend timeout, it should be
done in musb_core.c.

2430 glue layer")
