gru: set correct gpio for SD card detect
The only outlier at this time is Kevin rev 0, treat it specially, the rest of the targets use the same GPIO. BRANCH=none BUG=none TEST=gru still boots off SD card just fine Change-Id: Ic603093a990d27166b16175db3303f155b4775aa Signed-off-by: Martin Roth <martinroth@google.com> Original-Commit-Id: 5788c5add1d1f803e7b22fb53215b6003ac04d03 Original-Change-Id: Ic5183f08dd1119f9588f243bd9e9c080d84687f9 Original-Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/344151 Original-Reviewed-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: https://review.coreboot.org/14851 Tested-by: build bot (Jenkins) Reviewed-by: Vadim Bendebury <vbendeb@chromium.org>
