[PATCH v1] eSPI: add Aspeed AST2500 eSPI driver to boot a host with PCH runs on eSPI

When PCH works under eSPI mode, the PMC (Power Management Controller) in PCH is waiting for SUS_ACK from BMC after it alerts SUS_WARN. It is in dead loop if no SUS_ACK assert. This is the basic requirement for the BMC works as eSPI slave. Also for the host power on / off actions, from BMC side,
