tcpm: Call usb_mux board_init on exit from low power mode
PS8751 does not restore all register contents when resuming
from low power mode. This change makes tcpm call board_init
when it stops auto-toggling so that register contents can be
restored.
BUG=b:35585399
BRACH=none
TEST=On Snappy, the board_init funciton is called every time a device
is plugged in and register contents are restored.
