bus: ti-sysc: Do not disable on suspend for no-idle
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: 386cb76681ca ("bus: ti-sysc: Handle missed no-idle property in addition to no-idle-on-init") Reported-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
