The SPI driver can take as chip select the controller's chip selects as
well as an external GPIO. The LSB byte has the value of the internal
chip select, the highest (thought as 16-bit value) contains the GPIO
number. Reading this configuration, the GPIO used on this board should
be the number 83 (0x53).
