google/glados: fix kepler probing
On proto2 boards the kepler device has its reset line pulled up
to one of its IO rails with a zener in between. This results in the
device not being visible at MemoryInit() time because for some
reason FSP is doing PCIE configuration/probing in that path. Hack
around the broken FSP logic by configuring the pads for kepler's
power and clkreq.
BUG=chrome-os-partner:44326
BRANCH=None
TEST=Built and booted glados. lscpi shows the device on bus 2.
