geralt: remove pulldown on uart pins
The pull down affects base detection ADC voltage. Remove them temporarily. BUG=b:269989432 TEST=run command `adc adc-base-det` base detached: ~3.3V attached: 0.2V BRANCH=none Change-Id: I558466815840bbc6e74427d7ebe00dc8f186cff6 Signed-off-by: Ting Shen <phoenixshen@google.com> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/4322596 Reviewed-by: Eric Yilun Lin <yllin@google.com> Commit-Queue: Eric Yilun Lin <yllin@google.com> Auto-Submit: Ting Shen <phoenixshen@chromium.org> Tested-by: Ting Shen <phoenixshen@chromium.org>
