rambi: fix leakage on pp3300_pch_s5 rail
PWRBTN_L is pulled up to PP3300_PCH_S5 through a 30K resistor. However,
the PWRBTN_L pin was configured push-pull. So we are leaking into that
rail. Fix this by configuring it to be open drain.
BUG=chrome-os-partner:23221
BRANCH=None
TEST=Loaded new EC with change and noted the PP3300_PCH_S5_PG is driven
low correctly once the PP5000_DSW rail is up an SUSP_VR_EN=0.
