/*
* pxafb_minilcd_encode
*
* @brief this function encodes the pixels (RGB565) in the source buffers
* "src", with the geometry of width x height, into the destination "dst"
* (RGB555). The pixels will be run-length encoded. It returns the number
* of the encoded bytes if successful, or a negative number if failed.
*
* Note: this function assumes the destination buffer is large enough.
* This is usually true because the SRAM will only used by Mini-LCD in
* D1 power mode.
