Support of ESP32-P4

[VojtechBartoska]

This issue is tracking adding support of ESP32-P4.

Initial support for basic functions already merged in release/v3.1.x. Now working on checking if the peripherals work as expected and fixing what is found broken.

Oficial announcement is available here

---

ESP32-P4 is fully supported in ESP-IDF v5.3, this version is used in Arduino Core v3.1.0

Hello,

table updated, most of peripherals are already supported.

The ESP32-P4 has 16 or 32MB PSRAM built in. Is that picked up automatically if configured?
