Fix#22188
Introduce config option to disable automatic acknowledge via
virtual wires on response to eSPI host suspend and reset warnings.
This will give the opportunity for eSPI slave systems that need to
perform preparations before reset or suspend.

When a eSPI slave needs to send back-to-back packets
updating status signal need to guarantee both status
reach the eSPI host, i.e. SCI=0 followed by SCI=1.
This change guarantees both packets are transmitted
over esSPI bus.
Allow to map eSPI host logical UART to a soc UART.
