bus: ti-sysc: Do not disable on suspend for no-idle 



[ Upstream commit a55de412228cc5a2b4bf8d2a09849898102633e2 ]

If we have "ti,no-idle" specified for a module we must not disable
the the module on suspend to keep things backwards compatible.

Fixes: 386cb766 ("bus: ti-sysc: Handle missed no-idle property in addition to no-idle-on-init")
