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.
