drivers/intel/fsp2_0: Display FSP calls and status

Disable the chatty FSP behavior for normal builds.  Use a Kconfig value
to enable the display of the FSP call entry points, the call parameters
and the returned status for MemoryInit, SiliconInit and FspNotify. The
debug code is placed into drivers/intel/fsp2_0/debug.c.

TEST=Build and run on Galileo Gen2
