* INPUTS:   hReg7401 - 7401 register handle
*           
* OUTPUTS:  
* RETURNS:  none
* FUNCTION: This function configures the BCM7401 pin muxing for
*           BCM97401 reference board.
*           On the 7401, various GPIO pins are MUXed together with 
*           other pins, e.g. I2C, SPI, etc.  In order to make these pins 
*           function as I2C, SPI, etc. instead of GPIO, you have to write 
*           to the SUNDRY top control register.
