GPIO Ownership

Any PCH GPIO can be owned by the host, the Intel® CSE, or ISH depending on how the pin ownership being programmed. The programmed agent will then own the pin exclusively. For example, when a GPIO pad ownership is programmed to the Intel® CSE or ISH, the host software no longer has access to the pin programming.
