soc/intel/skylake: Add Kconfig option for LGA1151v2
Provide a SOC_INTEL_SKYLAKE_LGA1151_V2 option to select correct defaults for the combination of a Union Point PCH with LGA1151v2. As of the year 2021 it's common for motherboards with Z370, H310C or B365 PCHs, which are meant to be paired with Coffee Lake CPUs. Intel provides AmberLakeFspBinPkg to support this combination, which implements Intel FSP External Architecture Specification v2.1. Details: 1) Provide SOC_INTEL_SKYLAKE_LGA1151_V2 option that selects PLATFORM_USES_FSP2_1, SOC_INTEL_COMMON_SKYLAKE_BASE and SKYLAKE_SOC_PCH_H. 2) Add Amberlake FSP support. If SOC_INTEL_SKYLAKE_LGA1151_V2 is set, use AbmerLakeFspBinPkg instead of KabylakeFspBinPkg. 3) Enable Coffee Lake CPUs support. If SOC_INTEL_SKYLAKE_LGA1151_V2 is set, select MAINBOARD_SUPPORTS_COFFEELAKE_CPU. 4) Increase stack and heap size in CAR. If FSP_USES_CB_STACK is set (it's selected by PLATFORM_USES_FSP2_1), update DCACHE_BSP_STACK_SIZE and FSP_TEMP_RAM_SIZE values. 5) Update maximal number of supported CPUs. If MAINBOARD_SUPPORTS_COFFEELAKE_CPU is set, set MAX_CPUS to 16.
