boards/esp32s3: add support to M5Stack Cardputer board
This port adds support for the M5Stack Cardputer (M5Stamp S3 /
ESP32-S3FN8, dual Xtensa LX7 @ 240 MHz, 8 MB flash, no PSRAM).
It reuses the common ESP32-S3 board helpers and ships these
configurations:
- nsh: NuttShell over the USB-Serial-JTAG console
- sdcard: microSD card on SPI3 (FAT)
- fb: ST7789 240x135 display exposed as a framebuffer
- wifi: Wi-Fi station
- softap: Wi-Fi SoftAP with DHCP server
- lvgl: LVGL graphics on the ST7789 (lvgldemo)

+The `M5Stack Cardputer <https://docs.m5stack.com/en/core/Cardputer>`_ is a
+pocket-sized computer kit built around an M5Stamp S3 module (ESP32-S3FN8, dual
+Xtensa LX7 @ 240 MHz, 8 MB flash, no PSRAM). It integrates a 1.14" ST7789
+TFT, an NS4168 I2S speaker, an SPM1423 microphone, an IR transmitter, a
+microSD slot and a Grove port.

+Features
+========
+
+* ESP32-S3FN8 (dual Xtensa LX7 @ 240 MHz), 8 MB flash, no PSRAM
+* Wi-Fi 4 (2.4 GHz) and Bluetooth LE (native ESP32-S3 radio)
+* 1.14" 240x135 ST7789v2 TFT on SPI2
+* NS4168 mono I2S Class-D speaker amplifier
+* SPM1423 PDM microphone
+* IR transmitter, addressable RGB LED (WS2812)
+* microSD card slot (SPI) and Grove HY2.0-4P (I2C)
+* USB Type-C (native USB-Serial-JTAG)
+
+Serial Console
+==============
+
+By default the NSH console runs over the **USB-Serial-JTAG** peripheral exposed
+on the USB Type-C connector. It enumerates on the host as ``/dev/ttyACM0``
+(Linux). No external USB-to-UART bridge is required.

+
+Configurations
+==============
+
+All configurations use the USB-Serial-JTAG console and can be selected with::
+
+ ./tools/configure.sh esp32s3-m5-cardputer:<config>
+
+nsh
+ Basic NuttShell over USB-Serial-JTAG. Open the console
+ (``/dev/ttyACM0``) and interact with the shell::
+
+ nsh> help
+ nsh> ls /dev
+
+sdcard
+ NSH plus the microSD card on SPI3 (FAT), registered as ``/dev/mmcsd0``.
+ Mount it and access the files::
+
+ nsh> mount -t vfat /dev/mmcsd0 /mnt
+ nsh> ls /mnt
+ nsh> echo "hello" > /mnt/test.txt
+
+fb
+ ST7789 display exposed as a framebuffer (``/dev/fb0``). Run the
framebuffer
+ example to draw test patterns on the screen::
+
+ nsh> fb
+
+wifi
+ Wi-Fi station. Associate with an access point and obtain an address over
+ DHCP (replace ``<ssid>``/``<passphrase>`` with your network)::
+
+ nsh> wapi psk wlan0 <passphrase> 3
+ nsh> wapi essid wlan0 <ssid> 1
+ nsh> renew wlan0
+ nsh> ifconfig
+ nsh> ping 8.8.8.8
+
+softap
+ Wi-Fi SoftAP with a DHCP server. The board starts the access point
+ ``NuttX`` (WPA2/WPA3-SAE, passphrase ``nuttx12345``) at 10.0.0.1. Start
the
+ DHCP server so stations that join get an address::
+
+ nsh> ifconfig
+ nsh> dhcpd wlan0
+
+ Then connect a client to the ``NuttX`` network; it receives an address in
+ the 10.0.0.0/24 range and can reach the board at 10.0.0.1.
+
+lvgl
+ Graphics support with LVGL on the ST7789 display. Run the LVGL demo::
+
+ nsh> lvgldemo
