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.
