google/oak: Configure SD card detect pin with a pull-up
SD card detect pins should normally have a pull-up. It seems that for micro-SD cards this doesn't really matter all that much, but for the full-size slots we have on some Oak-derivatives (like Hana) it does. BRANCH=oak BUG=b:35854317 TEST=Booted Hana, confirmed that card detect no longer seemed stuck-on. Booted Elm and confirmed that SD card behavior didn't change.
