Keep the Elecrow's touch bus free of the USB PHY after Wi-Fi starts (0.2.94, firmware 0.2.80)

The GT911 of the CrowPanel 7.0" sits on GPIO 19 and 20, the ESP32-S3's USB pins. Firmware 0.2.79 freed them once, in a static constructor; the Wi-Fi PHY library then kept the USB PHY on (CONFIG_ESP_PHY_ENABLE_USB, on by default on an ESP32-S3) and the touch went quiet once Wi-Fi came up. The board file turns that option off, frees the pins again in BOOT_TOUCH after Wi-Fi started, and a one-second watchdog frees them whenever anything takes them, with a log line.
