bus: ti-sysc: Handle swsup idle mode quirks
In preparation of dropping interconnect target module platform data in favor of devicetree based data, we must pass swsup idle quirks to the platform data functions. For now, let's only tag the UART modules with the SWSUP_SIDLE_ACT quirk. The other modules will get tagged with swsup quirks as we drop the platform data and test the changes.
