soc/intel/apollolake: clarify Fast SPI CS2 pad configuration
The pad for CS2 of the Fast SPI interface needs to be configured for automatic MMIO translation when a SPI TPM is utilized. Instead of unconditionally configuring that pad under LPC_TPM provide a explicit Kconfig for a mainboard to select.
