common/block/cse: Add Kconfig to support ME specification version 21
This patch introduces Kconfig support for Intel's Management Engine
(ME), version 21. When 'SOC_INTEL_COMMON_BLOCK_ME_SPEC_21' is selected
it sets the ME_SPEC configuration to 18 because ME version 21 is
compatible with version 18 in terms of Host Firmware status registers.
