soc/intel/skylake: config ISH in SOC side 

Config ISH in SOC side by checking if ISH device is turned on.

"IshEnable" is not needed anymore since ISH device on/off will tell
if ISH should be enabled or not. "IshEnable" will be removed from chip.h
in separate CL.

Atlas board specific ISH setting is needed, which is committed in
separate CL.

BUG=b:79244403
BRANCH=none
TEST=Verified on Atlas board with ISH rework. ISH log showed on console.
