soc/intel/cannonlake: Add Whiskeylake SoC kconfig

This patch performs below tasks

1. Create SOC_INTEL_COMMON_CANNONLAKE_BASE kconfig.

2. Allow required SoC to select this kconfig to extend CANNONLAKE
SoC support and add incremental changes.

3. Select correct SoC support for hatch, sarien, cflrvps
and whlrvp.

* Hatch is WHL SoC based board
* Sarien is WHL SoC based board
* CFLRVP U/8/11 are CFL SoC based board
* WHLRVP is based on WHL SoC

4. Add correct FSP blobs path for WHL SoC based designs.
