soc: ti: Remove pm_runtime_irq_safe() usage for smartreflex
For the smartreflex device, we need to disable smartreflex on SoC idle, and have been using pm_runtime_irq_safe() to do that. But we want to remove the irq_safe usage as PM runtime takes a permanent usage count on the parent device with it. In order to remove the need for pm_runtime_irq_safe(), let's gate the clock directly in the driver. This removes the need to call PM runtime during idle, and allows us to switch to using CPU_PM in the following patch. Note that the smartreflex interconnect target module is configured for smart idle, but the clock does not have autoidle capability, and needs to be gated manually. If the clock supported autoidle, we would not need to even gate the clock. With this change, we can now remove the related quirk flags for ti-sysc also.
