igor.masar 37f58cf498 ci(usb/host): enable esp32s31 and esp32h4 for USB host examples
Remove the temporary esp32s31 disable from usb/host build-test rules.
Add esp32s31 and esp32h4 to the usb_host_msc and usb_host_lib pytest
matrices. Keep the tests temp-skipped in CI until usb_host_flash_disk
runners exist.

USB-OTG Examples

See the README.md file in the upper level examples directory for more information about examples.

Common Pin Assignments

Pin assignment is only needed for ESP chips that have a USB-OTG peripheral. If your board doesn't have a USB connector connected to the USB-OTG dedicated GPIOs, you may have to DIY a cable and connect D+ and D- to the pins listed below.

ESP BOARD       USB CONNECTOR (type A)
                   --
                  | || VBUS (5V)
[USB_DM]  ------> | || D-
[USB_DP]  ------> | || D+
                  | || GND
                   --

USB PHY pin mapping

USB_DP USB_DM
ESP32-S2/S3 GPIO20 GPIO19
ESP32-P4 2.0 pin 50 pin 49
ESP32-P4 1.1 GPIO27 GPIO26
ESP32-H4 GPIO22 GPIO21

Note: On the ESP32-P4, the USB 2.0 PHY pins are dedicated to USB-OTG functionality and cannot be used as general-purpose GPIOs.
