Subject: [PATCH] boards: esp32s3-lckfb-szpi: Remove obsolete device function
 prototypes

Remove function prototypes for BMP180 pressure sensor and CS4344 audio DAC
devices that were never actually present on this board configuration. This
cleans up the header file by removing declarations for non-existent hardware.

- * Input Parameters:
- *   port - The I2S port used for the device
- *
- * Returned Value:
- *   Zero is returned on success.  Otherwise, a negated errno value is
- *   returned to indicate the nature of the failure.
