soc/intel/cannonlake: Move the FSP related callbacks to separate files

Move funtions callbacks used to override FSP upd values to
separate files. This serves as a base change for SoCs for which
FSP is still under development, and hence the FSP header files
are not available yet and in turn the UPDs cannot be referred.
These newer SoCs will implement empty callbacks. The code will
compile with basic header files which only include the architectural
FSP structures.

This allows plugging in these separate files for compilation in an
environment where FSP header files are available.
The fact is, FSP header files are not released externally until PRQ.
However the teams at intel and some partners have access to the development
version of these files. This code refactor helps to continue development
on the pre-PRQ silicons and submit related code to coreboot.org.

BUG=None
BRANCH=None
TEST=Build for cnlrvp
