Add PM_DEVFREQ framework and governors to support dynamic frequency scaling for TI J7xxx SoCs. This enables:
- CONFIG_PM_DEVFREQ: Core device frequency scaling framework - CONFIG_DEVFREQ_GOV_SIMPLE_ONDEMAND: Simple ondemand governor - CONFIG_DEVFREQ_GOV_USERSPACE: Userspace governor for manual control These configurations allow the system to dynamically adjust device frequencies based on workload demands, improving power efficiency and thermal management.
