soc/intel/cmn/block/cse: Support sending EOP from payload

It has been observed that CSE might be busy and might require more time
to process the EOP command. Currently any boot time improvement in
coreboot leads to increase in EOP processing time hence add support for
sending EOP from payload in order to delay it as late as possible.

This improves boot time by ~10ms miliseconds.
