Subject: [PATCH] boards/lckfb-szpi-esp32s3: add gc0308 minimal defconfig

Add a minimal GC0308 camera configuration based on nsh. Unlike the
full camera config, this only enables the GC0308 DVP camera driver
(I2C, PCA9557, LEDC, CAM, VIDEO) and camcap example, without ADB,
SDMMC, LCD, PSRAM or other peripherals.

+------
+
+Minimal NuttShell configuration with GC0308 DVP camera support only.
+Based on the nsh configuration, this adds only the GC0308 image sensor
+driver, ESP32-S3 CAM DVP controller, and the V4L2 video pipeline.
+Console is accessible over UART0 (serial).
+
+You can run the configuration and compilation procedure::
+
+  $ ./tools/configure.sh lckfb-szpi-esp32s3:gc0308
+  $ make flash -j$(nproc) ESPTOOL_PORT=/dev/ttyUSB0
