soc/intel/skylake: Add option to control microcode update inclusion
On embedded boards the cpu mounted on the board is known. So it is not
required to include microcode for all possible Sky Lake and Kaby Lake
cpus. This patch provides the possibility to only support the versions
required.
By default all microcode updates will be included and the versions not
required can be removed using Kconfig.
