pd: ensure power role matches CC pull resistor after hard reset
pd: ensure power role matches CC pull resistor after hard reset

Make sure the power role and the CC pull resistor match after
receiving hard reset command in the middle of a swap.

BUG=none
BRANCH=samus
TEST=on samus connect left and right ports together with C to C
cable. note that after some collisions and some hard resets, it
eventually stabilizes with one port in SNK_READY, the other in
SRC_READY. without this CL, we get stuck executing a power swap
and our power role and CC resistor get out of sync, requiring
a reboot.
