soc/intel/tigerlake: Select PLATFORM_USES_FSP2_2
This patch performs below operations
1. Add support for FSP 2.2
2. Set EnableMultiPhaseSiliconInit to ensure bootloader can call
FspMultiPhaseSiInit() API.
3. Provide placeholder to perform require chipset programming (example TCSS)
before calling FspMultiPhaseSiInit() API.
