feat: add dfrobot board firebeetle2_esp32_s3

[tangjie133]

Description

Add board support for DFRobot FireBeetle 2 ESP32-S3 (DFR0975, N16R8) with:

• OV3660 DVP 8-bit camera (SCCB + DVP pin map from DFRobot wiki)
• DFR1092 3.5" 480×320 IPS display (ST7365P over SPI via GDI FPC)
• Backlight control on GPIO21

Changes

File	Purpose
board_info.yaml	Board metadata (ESP32-S3, DFRobot)
board_peripherals.yaml	I2C (camera SCCB), SPI (display), LEDC (backlight)
board_devices.yaml	Camera, display_lcd, lcd_brightness devices
sdkconfig.defaults.board	16 MB flash, 8 MB octal PSRAM, OV3660 DVP, display LCD
setup_device.c	Panel factory using esp_lcd_ili9488 IPS driver for ST7365P

Motivation

FireBeetle 2 ESP32-S3 is a common DFRobot dev board with an onboard camera connector and optional DFR1092 display. This enables esp-claw edge_agent on that hardware with camera capture and LCD output.

Notes

• Camera default format is set to 640×480 YUV422 instead of 1280×720 JPEG, because DVP DMA buffers need internal RAM and this board also runs display/LVGL (Emote).
• Display: ST7365P has no dedicated esp_lcd driver yet; panel is initialized through esp_lcd_ili9488 IPS path (same approach as DFRobot GDL).
• Board V1.2: Camera power is fixed on-board (no AXP313A PMIC control required).
• This PR is board configuration only (no changes to core camera/display modules).
