spring: Switch ID_MUX back on redetecting
spring: Switch ID_MUX back on redetecting

When we are redetecting, if ID_MUX is 1, we need to switch it back.
Otherwise, no one is there to switch it and we are stuck in this state.

BUG=None
TEST=Check the EC detects device type after redetecting from device type
0x60400.
BRANCH=Spring
