pd: add explicit setting of D+/D- switch when setting type-C muxes
Add explicit setting of USB D+/D- switch when setting the type-C
muxes. This fixes a bug in which we would open D+/D- switch when
entering DP mode and lose USB2.0 connection.
BUG=chrome-os-partner:39766
BRANCH=samus
TEST=add printf to board_set_usb_switches() on samus and make sure
we don't open the D+/D- switch when entering DP mode.
