> The following commits introduced a new implementation of ResetSystem ()

>  * 07fd95c9ca
>  * 0ad2f057d8

> The PchResetLib instance PeiPchResetLib links against ResetLib and already
> contained a definition of ResetSystem (). This resulted in a build failure in
> VS2017 due to multiple definitions of a symbol being provided to the linker.
> The failure did not reproduce in
> VS2015 so it persisted until now.
> 
> This change removes the pre-existing implementation of ResetSystem () in
> PchReset.c as it is now linked by the implementation in the ResetLib
> instance.
