servo_v4p1: Add mechanism to enable/disable USB3 to DUT
This CL disables USB3 to DUT by default.
It overwrites TUSB1064 usb_mux set method to always
prevent or allow using USB3 mode in this mux/switch.
This CL also adds console command (and needed backed)
that can be used to enable/disable USB3 to DUT.
BUG=b:254857085 b:263573379
BRANCH=none
TEST=build and flash servo FW
test functionality using Lazor board
