Majority of the chipsets do not have a dedicated GPIO to trigger
AP cold reset. Current code either ignores cold reset or does a warm
reset instead or have a work around to put AP in S5 and then bring
back to S0. In order to avoid the confusion, removed the cold reset
logic and only apreset is used hence forth.
BUG=b:72426192
BRANCH=none
TEST=make buildall -j
Manually tested on GLKRVP, apreset EC command can reset AP.
