- Remove GPTIMER and TIMG related definitions from soc_caps_full.h files - Move timer peripheral definitions to appropriate HAL layer files - Update references across components to use proper HAL abstractions - Consolidate timer group and GPTIMER capabilities organization - Ensure consistent timer configuration across all ESP32 variants This refactoring improves the separation of concerns between SOC capabilities and HAL implementations for timer-related functionality.
