usb_mux: Send DP safe mode info to virtual MUX
Before entering into alternate mode, state of the USB-C MUX needs to be

damaged or do not damage their Port Partner. Hence, sending the DP
safe mode info to virtual MUX from EC.

BRANCH=none
TEST=Manually tested on Intel RVP, MUX is able to configure to safe mode
before entering alternate mode.
