soc/intel/common: Fix long delay when ME is disabled
If the ME is disabled with the `me_state` CMOS setting, boot
times are approximately 5 seconds longer:
942:before sending EOP to ME 1,240,773 (5,599)
943:after sending EOP to ME 6,263,951 (5,023,177)
Total Time: 6,167,443
This is because the current code only checks if the ME is
disabled for CSE LITE SKUs. With this patch, boot times are
approximately 5 seconds quicker:
Total Time: 1,143,932
Tested on `starbook/adl` and `starbook/tgl`.
