soc/intel/cmn: Clear interrupt status after HECI-1 has been received
According to Intel doc#630774, BIOS should clear Host Interrupt Status
if it has read all the slots of the message from the ME circular buffer.
Since this is not found in client ME document, add a Kconfig
SOC_INTEL_CSE_SERVER_SKU that only clears interrupt status for Server
ME SKU.
On SPR-SP, if mainboard calls get_me_fw_version via HECI-1, with the
change can avoid seeing below Linux warning during boot with Linux
