servo_v4: Add console commands to override the HPD pass-through
New console commands, like:
> usbc_action dp hpd ext # use the external HPD, no overridden
> usbc_action dp hpd h # override HPD to high, IRQ pass-through
> usbc_action dp hpd l # override HPD to low, no IRQ pass-through
> usbc_action dp hpd irq # send HPD IRQ
BRANCH=servo
BUG=b:153647984
TEST=Tried the new console commands.
