imliubo fa153a8c82 boards: add M5Stack StickS3 board support ...

Add a complete board package under
application/basic_demo/boards/m5stack_sticks3/ for the
ESP32-S3-PICO-1-N8R8 based M5Stack StickS3.

Hardware:
  - 8 MB QIO flash @80MHz, 8 MB Octal PSRAM @80MHz
  - I2C0: SDA=47, SCL=48 (M5PM1 PMIC, ES8311 codec, BMI270 IMU)
  - I2S0 full-duplex: MCK=18, BCK=17, WS=15, DOUT=14, DIN=16
  - SPI3 LCD: MOSI=39, SCLK=40, CS=41, DC=45, RST=21
  - 1.14" ST7789 135x240 with (52,40) panel offset
  - Backlight on GPIO38 (active-high), LEDC PWM

Highlights:
  - M5PM1 PMIC modelled as a custom device; init sequence ported
    from M5GFX (disable I2C idle sleep, then bring up PYG2=LCD_PWR
    and PYG3=SPK_PA in push-pull output mode).
  - ES8311 declared as two audio_codec devices (DAC + ADC) sharing
    one I2C control line and one I2S port via YAML anchors,
    following the esp32_s3_korvo2l pattern.
  - ST7789 factory uses the IDF built-in esp_lcd_new_panel_st7789()
    and applies esp_lcd_panel_set_gap(52, 40) for the visible window.
  - ledc_backlight defaults to full duty (1023) so the panel is
    visible at boot — display.set_backlight() only toggles the
    LCD disp_on_off command and does not change LEDC duty.
