---------------------------
cpu: Ensure timing CPU sinks response before sending new request

This patch changes how the timing CPU deals with processing responses,
always scheduling an event, even if it is for the current tick. This
helps to avoid situations where a new request shows up before a
response is finished in the crossbar, and also is more in line with
any realistic behaviour.

Testing Done

All regressions pass.

Much more simple than I thought it would be. Thanks for the quick turn-around. 

Everything checks out on my end.
