Intel FSP: add a shared set of functions for the FSP

- Move the non chipset-specific fsp pieces out of the chipset into a
shared area.  This is used by northbridge / southbrige / SOC code.  It
pulls in pieces from Kconfig, Makefile and FSP specific code.
- Enabled in the CPU code with a Kconfig "select PLATFORM_USES_FSP"
