WAIT States from eSPI Target Device

There are situations when the target device cannot predict the length of the command packet from the master (PCH). For non-posted transactions, the target device is allowed to respond with a limited number of WAIT states.

A WAIT state is a 1-byte response code. They must be the first set of response byte from the target device after the TAR cycles.
