mainboard/google/poppy: Use sideband IRQ for SD Card Detect
Since SD card controller is expected to enter D3hot by runtime power
management if there is no card inserted, we need to use a sideband IRQ
pin which is not under the control of the controller. Thus, configure
GPP_A7 as the sideband IRQ pin and pass it to OS as the card detect
pin.
BUG=b:35586693
BRANCH=None
TEST=Verified on a reworked poppy board that card detect works fine.
