braswell: Tristate CFIO 139 and CFIO 140
CFIO 139 and CFIO 140 are consuming ~5 during stanndby. The reason
for this leakage is internally it is configured to 1K PU. So there
is leakage of ~2mW in standby. Total impact ~2.5 mw in Srandby.
Configure these CFIOs as tristate for ~5mW power saving at platform
level.
BRANCH=none
TEST=PnP Team to verify that the CFIO's are tri-stated.
