src/soc/intel/common: Clear GPIO driver ownership when not requested
The default state of the HOSTSW_OWN register in the PCH is zero, which
configures GPIO pins for ACPI ownership. The board variabt GPIO tables
can request specific pins to be configured for GPIO driver ownership.
This change sets the HOSTSW_OWN ownership bit when requested and
explicitly clears the ownership bit if not requested.
