mb/google/volteer: Pull up GPP_D16 instead of driving it
The latest realtek RTS5261 SD daughterboard exposes the PRSNT# pin to GPP_D16 but there is a RTS5261 requirement to pull up this pin and not drive it at power on. We can meet this requirement without breaking other boards by changing GPP_D16 to be a no-connect with an internal pull up. Other boards use this signal as an enable input, so changing this to pull up is OK. BUG=b:162722965 TEST=Verified RTS5261 and GL9755 daughterboards enumerate on PCI and can read SD cards.
