intel/fsp2_0: automatically split FSP into fsp{t,m,s}.bin

Automatically splited binary is used if all of the following are true:
- CONFIG_PLATFORM_USES_FSP2_0 is set
- supported processor family is used
- CONFIG_FSP_x_FILE is not set, so existing platform configs won't break.
Tested on custom board with Intel i7-6500U CPU.
