Remove the "OMAP_DEVICE_NO_IDLE_ON_SUSPEND" check, since
driver should be able to prevent idling of an omap device
whenever required.

Hi Kevin,
I have put this as an RFC, due to few comments on cover letter of
the previous version by Grygorii Strashko.
As, he has mentioned that there are Audio playback use cases which
also requires "no_idle_on_suspend" and using them on mainline after
this series can cause regression.
What you think will be the right approach on this in relation to this patch?
I mean every driver(if possible) should prevent
runtime PM for no_idle_on_suspend usecase and we get
rid of this OMAP_DEVICE_NO_IDLE_ON_SUSPEND check? OR we should
drop this patch as of now?
Hi Grygorii,
Is it possible to handle ABE no_idle_on_suspend uscase the way I am
trying to handle it for UART in the 2nd patch of this series?
