/**
* \brief This API function configures and enables the secondary SPI port.
*
* This port allows control compatibility with BBPs that employ dual SPI ports.
* The GPIO mapping for the SPI2 is fixed:
*  SPI signal  |   GPIO
* -------------|-------------------
*  CSB_2       |   GPIO 3
*  SCLK_2      |   GPIO 2
*  SDO_2       |   GPIO 1
*  SDO_2/SDI2  |   GPIO 0
*
* The secondary SPI port only has a small subset of registers that affect the
* attenuation of the TX channels. It uses a fifth GPIO pin in order to decide
* which TxAttenuation word is active. The Tx Attenuation words in the 2nd SPI
* port are different than the first SPI port.  On the 2nd SPI port, each
* transmitter has two Tx Attenuation words (an active word and an inactive
* word).  The BBIC should write to the inactive TxAttenuation word. Then the
* fifth GPIO pin should be asserted to make the inactive TxAttenuation word
* active.  This allows the BBIC to tightly control in real time when the
* TxAttenuation updates.
*
* <B>Dependencies</B>
* - device->spiSettings
* - device->spiSettings->chipSelectIndex
*
* \param device is a pointer to the device settings structure
* \param enable This is parameter will enable the secondary SPI port: 1 = enable, 0 = disable
* \param updateTxAttenPinSelect This parameter set the GPIO pin to be toggle for using the inactive attenuation words for both channels
*  tx update  |   GPIO
* ------------|-------------------
*     0x00    |   GPIO 4
*     0x01    |   GPIO 8
