soc/intel/apollolake: Consolidate ISH enabling

Browse Source 
Since the Integrated Sensor Hub can be disabled through devicetree.cb
as a PCI device, there is no need for a separate register variable.
Remove handling the register and update mainboards' devicetrees. Also
keep ISH disabled on both Reef and Amenia.
