soc/intel/skylake: Include some microcode blobs

This included the microcode for some CPUID's found in
soc/intel/skylake/bootblock/report_platform.c (others are likely pre-release
SKU's)

The amount of FIT entries needed is currently 7 so setting
CPU_INTEL_NUM_FIT_ENTRIES is set to a safe 10 will be able to fit them all.
