Add a no_irq_wake flag to struct tsens_plat_data to allow platforms to control whether TSENS interrupts should be configured as wakeup sources. Create a new data_automotive structure and add compatible strings for automotive TSENS variants (SA8775P, SA8255P) with wakeup interrupts disabled. Automotive platforms can enter a low-power parking suspend state where the application processors and thermal mitigation paths are not active. In this state, waking the system due to TSENS threshold interrupts does not enable useful thermal action, but it does repeatedly break suspend residency and increase battery drain. Allow these automotive variants to keep TSENS monitoring enabled during normal runtime while opting out of TSENS wakeup interrupts during suspend, so the system can remain in low power until ignition/resume.
