Chen Chen 675aa0695c feat(mcpwm): support mcpwm on esp32s31

- Remove duplicate 'MCPWM ETM timer event table' comment (esp32h2, esp32c6, esp32h21)
- esp32s31 clk_tree_defs: add PLL20M enum for MCPWM timer/capture/carrier to match SOC_MCPWM_*_CLKS

ESP Hardware Abstraction Layer for MCPWM Peripheral

Note

This component is currently in beta. Its API, behavior, and compatibility may change at any time and without notice; backward compatibility is not guaranteed. Use caution when integrating into production systems.

Overview

The ESP Hardware Abstraction Layer for Motor Control PWM Peripherals (esp_hal_mcpwm) provides a unified interface to interact with MCPWM (Motor Control Pulse Width Modulation) peripherals across all ESP chip families. This component abstracts the hardware-specific details of different MCPWM implementations, enabling consistent usage patterns regardless of the underlying hardware.

The component supports comprehensive MCPWM functionality including:

PWM signal generation with precise timing control
Dead-time insertion for motor control applications
Fault detection and protection mechanisms
Capture functionality for feedback systems
Synchronization between multiple MCPWM units
Event-driven operation modes
