ec/google/chromeec/ec_lpc: Declare used IO ports as a resource
Chrome EC uses IO ports 0x800 -> 0x9ff to communicate over LPC; however, those ports were not declared as a resource. This had two major downsides: * It allowed the allocator to assign said ports to other devices * It required manually open up an IO window in the LPC bridge. The LPC bridge on many chromeec boards had to be painstakingly adjusted to meet these constraints. The advantage of declaring the resources upfront is that the lpc bridge can now scan its child resources and automatically open up IO windows, as requested by its LPC children devices.
